2007 Lincoln Town Car Info Systems & Data Sheets

The 2007 Lincoln Town Car runs the same 4.6L SOHC two-valve Romeo block as the rest of the Panther platform, but tuned specifically for Town Car duty — 239 hp at 4,900 rpm and 287 lb-ft at 4,100 rpm, paired to the 4R75W four-speed automatic. Those output figures are higher than the civilian Crown Vic (224 hp / 272 lb-ft) and reflect a different PCM calibration, intake, and exhaust tuning optimized for the Town Car's long-wheelbase body and luxury NVH targets rather than police or taxi performance. The 2007 model year is the third year of the electronic throttle control era on the Panther platform — drive-by-wire has been standard since 2005 — and the Town Car's ETC implementation is mechanically identical to the Crown Vic and Grand Marquis, though several PCM pin assignments differ at the connector level. C175B pin 8, which carries the brake pedal position switch signal on the Crown Vic and Grand Marquis, is not used on the Town Car. C175T pin 21, which carries an engine vacuum signal on the Crown Vic, is also not used on the Town Car. C175B pin 14 carries an A/C clutch relay control signal that's specific to the Town Car's A/C architecture. The Town Car BJB uses Micro relays at positions 201–209 and Mini relays at 301–304 — different hardware from the Crown Vic and Grand Marquis's 1/2 ISO and Full ISO relays, which matters when sourcing replacements. The 2007 Town Car also retains the moonroof feed at BJB position 2, fog lamp relay at BJB 202, and has the power decklid module at BJB 108 — all Town Car-specific versus the P71/civilian Crown Vic split.

Engine Specifications

The 2007 Town Car runs the 4.6L two-valve SOHC Romeo V8 — same block and heads as the Crown Vic and Grand Marquis, but the PCM calibration, intake manifold, and exhaust tuning are specific to the Town Car application. The result is a higher output than the civilian Crown Vic: 239 hp versus 224, and 287 lb-ft of torque versus 272. Those gains reflect a more aggressive intake runner design and a calibration prioritizing mid-range torque delivery for the longer, heavier body. The ETC system is identical in hardware to the rest of the 2005–2011 Panther platform — same throttle body, same APP sensor configuration — but the PCM tune differs. All figures are SAE net.

Transmission Specifications

The 2007 Town Car uses the 4R75W — same unit as the 2005–2011 Crown Vic and Grand Marquis. The 4R75W replaced the earlier 4R70W across the Panther lineup starting in 2005, adding the turbine shaft speed (TSS) sensor at C175T pin 15, a stronger 24-lug ring gear, and a revised front pump. Gear ratios are unchanged from the 4R70W. The Town Car's 4R75W is tuned for the heavier body and longer wheelbase — shift firmness and TCC lockup programming differ from the Crown Vic in the PCM calibration, but the hardware is identical. Fluid spec is Mercon V throughout — do not use standard Mercon or Dexron in this unit. Lincoln used the Town Car extensively in livery, taxi, and limo service, making it a high-cycle application where the 150,000-mile ATF interval should be treated as an absolute maximum, not a guideline.

Battery Junction Box Fuse Panel Data & Info

Location: Engine bay, passenger side, behind battery | All information verified with AllData.

The Battery Junction Box (BJB) on the 2007 Town Car serves the same role as on any Panther-platform car — under-hood high-current distribution for the starter relay, cooling fan, ABS pump, blower relay, defroster relay, PCM power chain, and the two main feeds (BJB 103 and 104) that power the interior CJB. The Town Car BJB layout for 2007 differs from the Crown Vic in several meaningful ways: position 2 carries moonroof and rear heated seat feeds (not a police-only spot light circuit), position 5 is the I/P power point (not RASM/VAPS as on the Crown Vic), position 108 is the Power Decklid Module (PDM) at 40A, and positions 111–115 carry rear power points, air compressor, rear cigar lighters, and the I/P fuse box feed #3 — civilian comfort circuits the police-spec Crown Vic doesn't have. The relay format is also different: Micro relays at 201–209, Mini relays at 301–304. These are physically smaller than the 1/2 ISO and Full ISO relays used in the Crown Vic and Grand Marquis — do not cross-substitute. Sourcing the wrong format relay will leave the socket unpopulated or require adapters.

The same moisture and heat failure modes that affect all Panther BJBs apply here, but Town Car BJB failures have an additional livery context: high-mileage Town Cars used in taxi or limo service see far more thermal cycling and vibration than civilian Crown Vics. The PDM circuit at BJB 108 (40A) is a common fault point on high-mileage Town Cars — the trunk lid solenoid and pulldown module draw consistent current from this feed, and corrosion at the fuse legs or bus contact will show up as intermittent power decklid failures before the fuse actually blows. Check for voltage drop at BJB 108 under load if the decklid is sluggish or intermittent before replacing the PDM itself. The same voltage-drop discipline applies to all BJB feeds: anything over 0.1–0.2V across a connection under load indicates resistance that will eventually generate heat and escalate the problem.

Powertrain Control Module (PCM/ECU) Data & Info

Location: Engine bay, driver's side inner fender | All information verified with AllData.

The 2007 Town Car PCM uses the same three-connector 150-pin layout as all 2005–2011 Panther-platform vehicles — C175T (left, black, part 12B637), C175B (center, black, part 14290), C175E (right, black, part 12B637) — but several pin assignments differ from the Crown Vic and Grand Marquis, and using the wrong model's pinout during diagnosis will send you in the wrong direction. The most important Town Car-specific differences: C175B pin 8 is not used on the Town Car (the Crown Vic and Grand Marquis use this pin for the brake pedal position switch signal). C175B pin 14 carries an A/C clutch relay control signal (OG/LB, circuit 73, 20 ga) that does not appear in the Crown Vic pinout — the Town Car's A/C relay control circuit is routed through the PCM differently. C175T pin 21 is not used on the Town Car (the Crown Vic uses it for an engine vacuum signal). These three differences alone account for a significant percentage of PCM wiring misdiagnoses when technicians use a generic Panther pinout without confirming the model.

C175B handles the ETC system (APP sensors 1–3 at pins 5, 17, 28; ETC Vref 1 and 2 at pins 4 and 24; signal return at pin 6), the HS CAN bus (pins 11 and 23), fuel pump monitoring (pins 12 and 21), starter relay control (pin 2), and the ground cluster at pins 47–50 (BK/WH, circuit 570, 18 ga). The ground cluster is the same critical diagnostic starting point as on all Panther PCMs — four grounds at a single node, and any resistance here produces wide-ranging, hard-to-attribute symptoms. C175E carries all eight coil-on-plug outputs, all eight injector controls, the downstream O2 sensors, MAF, IAT, CHT, crank and cam position sensors, knock sensors, MAP, DPFE, and both ETC motor drive signals (pins 34 and 51 at 18 ga). The Town Car retains EGR at C175E pin 21 (DPFE sensor input) and the EVR solenoid control at pin 63.

On a 2007 Town Car with livery or high-mileage history, connector corrosion at C175B is the most common PCM-adjacent failure. High-cycle taxi and limo use means the harness and connectors age faster than on a typical civilian car. Start at the C175B ground cluster (pins 47–50) with a voltage-drop test engine running — anything above 0.1V on any pin needs attention before any other PCM diagnosis. Also check C175B pins 35 and 36 (RD, circuit 361, switched run/start voltage) and pin 45 (RD/WH, circuit 729, constant battery feed) under load. The 2007 Town Car PCM is VIN-programmed and requires reflash after replacement — it is not a plug-and-play swap. Ford's IDS or a J2534 pass-thru device is required.

Central Junction Fuse Box Data & Info

Location: Driver's side compartment, under steering wheel | All information verified with AllData.

The Central Junction Box (CJB) on the 2007 Town Car — also referred to as the instrument panel fuse box or I/P fuse box — is the interior counterpart to the under-hood BJB. It distributes switched and unswitched power to the cabin electronics: lighting control module, HVAC, wiper motor, audio and navigation, door modules, PATS transceiver, seat modules, restraints module, and more. The Town Car CJB layout for 2007 differs meaningfully from the Crown Vic: position 1 adds the starter relay coil to the DTR sensor feed, position 6 adds PCM power relay and fuel pump relay to the PATS circuit, position 8 adds the Power Decklid Module (PDM), overdrive cancel switch, cluster, and compass module, and position 19 includes the Liftgate/Trunk Module (LTM) and Driver Seat Module (DSM) — none of which appear in the Crown Vic CJB for this year. The Town Car does not have the Crown Vic's police-specific positions (29, 30, 32). Position 32 is instead a 7.5A delayed accessory feed for navigation, audio, and moonroof — a luxury-spec circuit absent on the police car.

The same water intrusion failure mode that affects Crown Vic CJBs applies here, but Town Car livery use adds a layer: high-cycle vehicles see more connector flex, vibration, and thermal cycling than civilian cars. The PDM circuit (CJB 8) is a common source of intermittent decklid behavior on high-mileage Town Cars — if the decklid opens sluggishly or fails to latch consistently, check voltage at CJB fuse 8 under load and inspect the connector for corrosion before replacing the PDM module. The same two-step process applies across all CJB faults: find and eliminate the water source first, then inspect connectors and replace damaged terminals. Cleaning corroded contacts on a Town Car that's seen years of livery duty only delays the next failure.

Trim Level Fuse Differences

The 2007 Lincoln Town Car was offered in four trim levels: Executive, Signature, Signature Limited, and Signature L (long wheelbase). The Executive is the base trim with fewer comfort features. The Signature and Signature Limited add heated and cooled seats, upgraded audio, rear climate controls, and memory seat systems. The Signature L adds the extended wheelbase with additional rear passenger features. Several fuse and relay positions are populated differently depending on which features are equipped — if you're working on a Town Car and the fuse layout doesn't match what's in the diagram, the trim level is the first thing to confirm.

Known Issues & TSB Reference

The items below are documented issues Ford and Lincoln acknowledged for the 2007 Town Car — through Technical Service Bulletins (TSBs), extended warranty coverage, or pattern failures well-established in the platform community. This is not a complete TSB list, but covers the issues most relevant to someone maintaining or diagnosing a 2007. Full TSB text is available through ALLDATA, Mitchell1, or your local Ford/Lincoln dealer's service department.

Scheduled Maintenance Intervals

The intervals below reflect Ford's Normal Schedule for the 2007 Lincoln Town Car. Normal schedule applies to typical everyday driving. Vehicles used for livery, taxi, or limousine service — which describes a large percentage of surviving 2007 Town Cars — are Special Operating Conditions vehicles and require significantly shorter intervals, particularly on engine oil, transmission fluid, and brake inspection. A Town Car with livery history is not a normal-schedule car regardless of what the odometer reads.
