Ford GT Engine Crankshaft Position Sensor Guide (2005-2006)
Keep your Ford GT's 5.4L V8 running precisely with the right crankshaft position sensor.
- This guide is for the 2005-2006 Ford GT; the year range 2005-2012 is incorrect for this model.
- For a critical part on this engine, choose a top-tier aftermarket brand like Denso, NGK/NTK, or Delphi for reliability.
- Symptoms like stalling, no-start, and a rough idle are common signs of failure and should be addressed immediately.
- There are no known recalls or TSBs for the crankshaft position sensor on this vehicle; all recalls relate to airbags.
A Note on Vehicle Years
This article is for the first-generation Ford GT, which was produced for the 2005 and 2006 model years. While some parts databases may group it into a wider year range, all specific information here applies to the 2005-2006 models equipped with the 5.4L supercharged V8 engine.
Symptoms of a Failing Crankshaft Position Sensor
A bad crankshaft position sensor can cause major problems. Because it's so important for engine timing, a failure will be noticeable. You should not ignore these signs, as a complete failure can leave you stranded.
- Engine Won't Start: The engine cranks but never fires up because the computer doesn't know when to send spark and fuel.
- Intermittent Stalling: The engine may shut off unexpectedly while you are driving or idling. This is a serious safety issue, as it can cause a loss of power steering and power brakes.
- Check Engine Light: A failing sensor will almost always trigger a Check Engine Light. The most common code associated with this part is P0335 (Crankshaft Position Sensor 'A' Circuit Malfunction).
- Rough Idle and Misfires: The engine may shake, run unevenly, or sound like it's sputtering at a stop.
- Poor Acceleration: You may feel a significant loss of power, hesitation, or sluggishness when you press the gas pedal.
Choosing the Right Aftermarket Sensor
For a high-performance, high-value vehicle like the Ford GT, part quality is essential. While an OEM sensor from Ford is always a safe bet, several aftermarket brands offer excellent quality, sometimes from the same factories that make the original part. Here’s how the available brands generally stack up based on reputation for critical electronic sensors.
A Mechanic's Advice
For a critical sensor on an engine like the GT's 5.4L V8, it is strongly recommended to choose a brand from the OEM-Quality or Trusted Aftermarket tiers. While budget parts are available, the risk of premature failure, poor performance, or getting stranded outweighs the small cost savings.
Tier 1: OEM-Quality Aftermarket
These brands are often original equipment suppliers to major automakers and are known for their reliability and precision. They are the best choice outside of buying the part directly from a Ford dealer.
- Denso: A top-tier global OE supplier known for exceptional quality and engineering. Denso sensors are often considered as good as or better than the original factory part.
- NGK / NTK: NTK is the sensor division of NGK. They are highly regarded for producing reliable, OE-spec sensors that perform flawlessly with sensitive engine computers.
- Delphi: Another major OE supplier with a strong reputation for engine management components.
Tier 2: Trusted Aftermarket Brands
These brands have a long history in the aftermarket and are generally considered reliable choices for daily drivers and performance vehicles.
- Standard Motor Products (SMP): A well-known brand that often provides quality parts. Some of their products are even re-boxed OEM parts. However, be aware of their different product lines; avoid their budget "T-Series" if possible, as its quality can be inconsistent.
- Hitachi: A known OEM supplier for many Japanese vehicles, they also produce quality sensors for other applications.
Tier 3: Standard & Economy Brands
These brands provide a functional part at a lower cost. They can be a viable option, but may not have the same long-term durability or precise calibration as higher-tier brands.
- Dorman: Known for providing a wide range of cost-effective aftermarket parts. While many products are reliable, quality on electronic sensors can be inconsistent compared to OE-focused brands.
- Walker Products, Holstein, Prenco, Spectra, True Tech: These brands typically fall into the standard replacement category. They meet the basic fit and function requirements for the part.
Known Issues, Recalls, and Bulletins
As of early 2026, there are no active recalls or Technical Service Bulletins (TSBs) from Ford or the NHTSA specifically for the engine crankshaft position sensor on the 2005-2006 Ford GT. All major recalls for this vehicle have been related to Takata airbag inflators.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $22.51 - $48.36 |
| New OEM (Ford) | $45 - $75 |
| Shop Labor | $75 - $150 |
Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor located on the Ford GT?
The sensor is mounted on the front of the engine, typically on the timing chain cover near the main crankshaft pulley (harmonic balancer). It is usually held in by a single bolt and is accessible from underneath the vehicle.
Do I need to perform a 'relearn' procedure after replacing the sensor?
For the 5.4L engine in this generation, a specific manual relearn procedure is not typically required for the crankshaft position sensor itself. The PCM will adapt to the new sensor after a few drive cycles. However, clearing the fault codes with a scan tool after installation is always recommended.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, this is a very feasible DIY job. It typically involves safely raising the front of the vehicle, removing a splash shield, locating the sensor, undoing one bolt, and disconnecting the electrical connector. The difficulty is low, assuming the bolt is not seized.
What is the most common mistake when ordering this part?
The most common mistake is confusing the crankshaft position sensor with the camshaft position sensors. The 5.4L V8 has one crankshaft sensor but two camshaft sensors (one for each cylinder bank). Ensure the part you are ordering is explicitly for the 'crankshaft' position.
Technical Specifications
OEM Part Numbers: 4G7Z-6C315-A AA5Z-6C315-A AT4Z-6C315-A 7T4Z-6C315-B
This is a two-wire variable reluctance sensor that reads a toothed wheel on the crankshaft to determine engine speed and position.
