  • A few codes on my BP

    So it's time to stop being lazy and fix this CEL before it gets too cold. I checked the codes, and I'm getting these:

    02 - No crankshaft position sensor signal
    03 - No Cylinder ID sensor signal
    15 - Exhaust gas oxygen sensor - voltage stays below 0.55 volts (lean)
    17 - Exhaust gas oxygen sensor - voltage does not change (rich)

    I'm assuming the issue with the O2 sensor is my manifold. The threads were stripped, and I just forced the sensor in there. I'll replace that with a header, before I try to diagnose it. This looks decent.

    As for the other two, I have no idea what they are. Haynes manual doesn't give much information. A search yieled Code 03 being related to the Disty, with not much other information. Any help is very appreciated!
    BP, Aspire brakes, stock trans.

    You probably have to have the crankshaft re-timed. or replace the sensor....not a big deal either way.

    alot of times one issue can cause a bunch of codes to appear. I would start with the crankshaft code first then run the codes again.
