What is a ECM PCM power relay?
What is a ECM PCM power relay?
The ECM power relay, or the PCM relay, acts as a switch that provides power to the ECM. when the ignition key is turned off, the switches within the PCM relay no longer receive battery. If the PCM relay stops switching and working like it should, the vehicle will not be able to function properly.
When do I get an error code p0690?
Error Code P0690 is stored when the PCM has determined an abnormality in the relay which supplies it with voltage. This code particularly means the power relay sensor circuit voltage exceeds the maximum allowable parameter.
What causes a p0690 Chevrolet engine to light up?
P0690 CHEVROLET Possible Causes Weak battery Low voltage while cranking Faulty Engine Control Module (ECM) power relay ECM power relay harness is open or shorted ECM power relay circuit poor electrical connection Blown ECM fuse Faulty ECM
When is a power relay code p0690 stored?
When a code P0690 is stored, it means that the powertrain control module (PCM), has detected an abnormality in the relay which supplies it with voltage. This particular code will be stored if power relay sensor circuit voltage exceeds the maximum allowable parameter.
How much does it cost to repair a p0690 Chevy engine?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P0690 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

What does the p0690 code on a car mean?
What the P0690 code means. P0690 is an OBD-II generic code for a high voltage problem with the power supply to the ECM/PCM. This means the vehicle’s computer is not receiving voltage that is within the manufacturer’s parameters.
When a code P0690 is stored, it means that the powertrain control module (PCM), has detected an abnormality in the relay which supplies it with voltage. This particular code will be stored if power relay sensor circuit voltage exceeds the maximum allowable parameter.
