    Crankshaft Position Sensor & Camshaft Position Sensor, Labor Involved?

    Hi Folks, I am wondering what is involved in terms of labor to replace a crankshaft and camshaft position sensor?

    What has to come out to gain access to these two sensors?

    Thank you,
    Luke

    cam sensor is a piece of cake, one bolt nothing needs to be taken off to change it, it is located on the front of the engine near the coolent cross over. The crank sensor is a bit more work but not bad at all, you need to pull the a/c comp off ( 3 bolts ... I think ) and then the sensor is just one bolt. Both sensor bolts are a 10mm if I remember correctly. hope this helps.

    Basic handle tools. Shouldn't take you more than 20 minutes at most.

    Thanks guys.

    If anyone is following my project thread, I am experiencing a problem where the car is not fully running commanded spark. The tuner has the knock sensors turned off and is reporting that the car is showing spark (in the datalogs) that is several degrees lower than he wrote into the tune.

    He suggested I begin by looking at these two sensors.

    Could they affect the way timing comes on?

    I'm not so sure you have to remove the A/C compressor in order to remove the crank sensor

    +1, it's usually a wiring issue.

    How many of those were covered in leaking oil and sludge?

    Just curious if it was a bad connection or actually the sensor.

    they were all dirty- but a simple sensor replacement seemed to do the trick

    Does anyone know if these sensors could potentially affect spark advance without throwing any codes?

    I've had to replace the cam and crank sensors in both of my 4V motors.

    Just curious, what were the symptoms? I assume you got a code?

    They were not communicating with the PCM. I tested this via both my Autoboss and Genisys and both of them could not establish a connection with the cam and crank sensors. An easy way of checking this for most people (those that can't get ahold of scanning equipment) is to try and datalog both sensors or you can replace the sensors with a known working one to see if communication is reestablished.

    Granted my BAB Cobra fiasco was screwed up from the moment I got the car but nevertheless they were replaced with Motorsport pieces.

    Edit: I also noticed that connectors on the cam and crank sensors were fairly brittle and the connectors didn't hold the sensor very snugly.

    So did it throw a code?

    No. The vehicle would not crank.
