- Evaluated for signal compatibility with Ford PCM
Pros: Lower price point; Easy installation with included hardware; Widely available
Cons: Shorter lifespan reported by some users; May require slight modification for perfect fit
3. ACDelco 213-468: Premium Choice
The ACDelco 213-468 is a premium aftermarket sensor designed for high-performance or heavy-duty applications. Its brass core and high-temperature rating make it stand out in our evaluation. Owner feedback indicates it maintains consistent signal output even under extreme engine bay heat, which is critical for the 7.3L Powerstroke known for high under-hood temperatures. The sensor undergoes rigorous testing to meet ACDelco’s quality standards.
On the downside, the price is significantly higher than many aftermarket options, approaching OEM levels. Some users reported that the body is slightly thicker than stock, requiring careful alignment during installation. If you run a modified or heavily used 7.3L and need maximum heat resistance, this sensor is worth the investment. Skip it if you have a stock engine and are not experiencing heat-related issues, as the extra cost may not be justified.
- Brass core for superior heat dissipation
- High-temperature rated up to 300°F

Frequently Asked Questions
What are the symptoms of a bad 7.3 camshaft position sensor?
Common symptoms include intermittent stalling, hard starting, rough idle, loss of power, and the check engine light illuminating with code P0340 or P0341. The engine may also die while driving and then restart after a few minutes.
How do I test a 7.3 camshaft position sensor?
You can test the sensor using a multimeter to check resistance and voltage output. With the sensor removed, measure resistance between the signal and ground pins; it should typically be between 400-600 ohms. You can also perform a cranking voltage test to see if the sensor produces an AC voltage signal.
Can I replace the 7.3 camshaft position sensor myself?
Yes, it is a straightforward DIY job. The sensor is located on the front of the engine near the harmonic balancer. You need a socket, ratchet, and possibly a small pry bar. Disconnect the battery, unplug the connector, remove the retaining bolt, and pull out the old sensor. Install the new one with a new O-ring, torque the bolt to spec, and reconnect.
Will a bad cam sensor cause no start?
Yes, a failed camshaft position sensor can prevent the engine from starting. The PCM uses the cam sensor signal along with the crank sensor to determine injection timing. Without a valid cam signal, the PCM may not fire the injectors, resulting in a no-start condition.
How often should I replace the 7.3 camshaft position sensor?
There is no set replacement interval. OEM sensors often last 100,000 miles or more. Aftermarket sensors may need replacement sooner, typically between 30,000 and 60,000 miles. If you experience symptoms, it is wise to replace it proactively to avoid being stranded.
