    Question 01 Catera turns over but won't start. Got code P1530

    My car's turning over but not starting and the check engine light came on. I scanned and got code P1530: Ignition Timing Adjustment Switch Circuit.

    Any suggestions?

    It seems to point to Throttle Position (TP) sensor as well as the throttle body movement.

    I always start with checking connectors for sensors first. Throttle body you need to verify that it is not stuck. It needs to move under the throttle control mechanism and is spring loaded to not move totally freely.

    Hope it helps as you appear to be quite knowledgeable regardless.
