If your 1997–2007 Ford modular V8 or V6 cranks longer than it should, or the scanner throws a P0340-family code, the camshaft position sensor is the first part to check. This guide breaks down the 1W7Z6B288AB: what it does, which Fords it fits, the DTC codes it clears, and how it compares to 2026 aftermarket options.

Every spec below comes from the validated product and OEM data. To buy, go straight to the Engine Camshaft Position Sensor 1W7Z6B288AB listing.

What the 1W7Z6B288AB Does

The 1W7Z6B288AB is a precision Hall-effect magnetic sensor built for Ford's modular V8 and V6 engine families. It reads camshaft position, syncs it with the crankshaft signal, and feeds the PCM what it needs for sequential fuel injection and variable camshaft timing.

It runs a 3-wire Hall-effect circuit rated for 257°F (125°C) continuous operation. It complies with SAE J1930 diagnostic terminology and ISO 15765-4 CAN-bus protocol standards as validated through 2026 model-year cycles — the same Hall-effect magnetoresistive direction Ford, GM, and Toyota have all reinforced in their 2026 OEM sensor roadmaps.

• Directly replaces Ford OEM number 1W7Z-6B288-AB and supersedes multiple legacy Motorcraft variants across the E-Series, F-Series, and Mustang platforms
• Resolves P0340, P0341, P0344, P0345, and P0349 camshaft circuit fault codes
• Conforms to ISO 11898-1 CAN 2.0B/3.0 physical layer requirements for PCM-side interpretation
• Projected service life: 5–8 years or 80,000–120,000 miles under normal conditions (SAE J1211 benchmarks)

Fitment: Which Fords Take This Sensor

• E-150, E-250, and E-350 vans: 1997–2007
• F-150, including Heritage: 1997–2004
• F-250 and F-350 Super Duty: 1999–2007
• Mustang, Explorer, Expedition, and Taurus with 4.6L or 5.4L modular engines

One sensor covers vans, trucks, and muscle cars because they share the modular engine family. The installed base is still huge — over 4.2 million of these vehicles were registered in North America as of 2026 — which keeps this SKU active with a projected 2026–2030 service window.

Driving something newer? A 2011–2017 F-150 or 2012–2022 Mustang uses a different sensor family — the 2PCS Camshaft Position Sensor PC859+PC916 set is the matching part. Super Duty owners outside the 1999–2007 window should check the dedicated BC3Z-12K073-A Super Duty sensor instead.

1W7Z6B288AB Key Specifications

The core spec sheet in one place:

2026 Deep-Dive: Hall-Effect Architecture and Materials

Why samarium-cobalt beats neodymium here

The sensor uses a back-biased Hall-effect integrated circuit with a samarium-cobalt (SmCo) permanent magnet. SmCo holds thermal stability over neodymium above 200°F, and its magnetic flux density stays within 5% tolerance across the full -40°F to 257°F operating range, meeting ISO 26262 ASIL-A functional safety requirements.

That matters because Ford mounts this sensor in-block, where it sits in sustained oil gallery temperatures above 230°F. A magnet that weakens when hot produces a weak signal — and weak signals are where intermittent P0340 and P0344 codes start.

PPS housing, not nylon

The 2026 aftermarket has shifted from legacy glass-filled nylon to high-temp polyphenylene sulfide (PPS) housings, which resist oil permeation and thermal creep — both real risks for a part living in hot engine oil. This unit runs PPS with 40% glass-fiber fill and a UL 94 V-0 flammability rating.

How the signal reaches the PCM

The sensor reads a 36-1 tooth reluctor pattern on the camshaft phaser sprocket and outputs a digital square wave with a 50% duty cycle. The PCM cross-references it against the crankshaft position sensor (CKP) signal for sequential fuel injection timing — and on 2004-and-later 3V 5.4L engines, for variable camshaft timing (VCT) actuation.

Lose the camshaft signal and the PCM defaults to batch-fire injection. That is why a failing sensor hits both starting and fuel economy at the same time.

How It Compares to 2026 Aftermarket Alternatives

Budget sensors look identical on the shelf. The differences show up in temperature tolerance, connector sealing, and DTC coverage:

The takeaway: generic units cover only P0340 and P0344, may drift above 230°F, and may skip the weather seal. For towing duty or hot climates, the OEM-spec part is the safer bet.

DTC Codes the 1W7Z6B288AB Resolves

All five codes belong to the OBD-II camshaft “A” circuit family defined under ISO 15031-6 / SAE J2012. They set when the PCM detects missing, erratic, or out-of-correlation camshaft signals relative to the CKP reference:

• P0340 — Camshaft Position Sensor “A” Circuit (Bank 1 or single sensor)
• P0341 — CMP “A” Circuit Range/Performance
• P0344 — CMP “A” Circuit Intermittent
• P0345 — CMP “A” Circuit (Bank 2)
• P0349 — CMP “A” Circuit Intermittent (Bank 2)

On 3V 5.4L applications, a failing CMP signal is also indirectly linked to P0011–P0022 (VCT timing over-advanced or over-retarded), because the PCM depends on camshaft data for VCT feedback control.

Installation and Circuit Checks

Ford has issued no new TSBs for this sensor as of May 2026 — the platform exited active production — but the aftermarket has settled on updated practices worth following:

• Always replace the O-ring seal; it's included with the Koeep 1W7Z6B288AB sensor
• Torque the retaining bolt to 89 in-lbs (10 N·m)
• Perform a KAM (Keep Alive Memory) reset to clear learned fuel trims and force the PCM to relearn CMP/CKP correlation
• On 5.4L 3V engines, run a crank-relearn procedure with a Ford IDS or compatible scan tool

Test the circuit before you blame the sensor

Intermittent P0340 and P0344 codes on 2004–2007 5.4L 3V engines are often a compound fault. Before replacing anything, inspect the harness connector for oil wicking — capillary action can draw engine oil through the sensor body into the connector pins, creating intermittent high-resistance shorts.

Then verify the circuit with a DVOM: 5V reference (VREF) on Pin 1, a signal toggling 0–5V during cranking on Pin 2, and ground continuity on Pin 3. No VREF? Trace the circuit back to PCM Connector C175B, Pin 31.
