Ive started to get this code on cold starts. After research im told that is sensor is located inside the distributor and is not a serviceable part. . After i reset the ECU i can drive where ever and turn the car off and restart it, but after a 3-4 hours of sitting or more it will pop the code on start up. I did plugs wires cap and rotor and still had a hesitation so i replaced the distributor with a Cardone New replacement. set the timing per the manual and all was well for 3-4k miles, but and now this is happening.
