<<See All OBD Codes

The P0697 trouble code can be defined as Sensor Reference Voltage “C” Circuit/Open. Here the “C” would denote a particular area of the circuit.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

Willing to learn more about this fault code? The error code P0697 is related to computer output circuit issues and would start appearing if there is an internal computer failure. Now here in this case, it is the engine control module which has detected some defect in the sensor reference voltage “C” circuit.

What causes this problem with the Sensor Reference Voltage “C” Circuit/Open?

• There can be defective, open, or shorted wiring and connectors between control modules
• Open or shorted wiring and connectors between engine sensors
• Some faults in the engine control module

Here are some steps which you should follow in order to diagnose this fault code:

• You will require an OBD-II scanner to check for a stored P0697 error code
• Then you should use a complete wiring schematic specific to your vehicle’s specific make and model
• All the related wiring and electrical components should be visually inspected for the damage
• Utilize a specialized scanner, such as a Tech II, which would help locate the general area of the fault
• A memory saving device should be used to ensure other controllers do not lose memory during reprogramming
• Use a diagnostic CAN scanner to see pin values and which control modules are activating
• Carefully inspect the disconnected or faulty or system grounds
• Make sure that you check the corroded or loose electrical connectors due to which there is an increase in the circuit resistance

Common Mistakes When Diagnosing The P0697 Code

• Make sure that you always diagnose and repair codes in the same order in which they have been stored, as subsequent codes may simply be a symptom of a larger issue
