    Help. I have a '96 4x4 Tacoma SR5, 3.4 5VZFE non California model (no EGR system). with error codes P0325 & P0330.
    Have changed both knock sensors (Matsushita from Oreilly's) and lower harness (from Toyota). Still have the error codes. Tested the wiring harness for shorts to ground and continuity. Bypassed the wires from the lower harness connection to the ECM connector. No change, still have the codes.
    Is there anything else in the system that could cause the P0325 & 330 codes?
    How to test or diagnose if the problem is with the ECM?

    Thanks for any help and suggestions.
