    What does P0690 Mean?

    OBD-II Code Hard or no start in cold weather is defined as a ECM/PCM Power Relay Sense Circuit High

    The engine computer (PCM) power relay controls battery voltage to the PCM. If the PCM detects an incorrect voltage signal from the power relay, it will set code P0690.

    How do you troubleshoot P0690 ?

    Use the DVOM to test resistance and continuity on all system circuits if actuator and sensor resistance levels are in compliance with manufacturer's specifications. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
