P0697 CHRYSLER – 5 Volt Reference 3 Circuit

P0697 CHRYSLER Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P0697 CHRYSLER Possible Causes

Faulty Engine Control Module (ECM),ECM harness is open or shorted,ECM circuit poor electrical connection,Shorted sensor on 5 volt circuit

P0697 CHRYSLER Description

The control module has internal 5-volt reference buses called 5-volt reference . Each reference bus provided 5-volt reference circuit for more than one sensor. Therefore, a fault condition on one 5-volt reference circuit will affect the other 5-volt reference circuits connected to the reference bus. The control module monitors the voltage on the 5-volt reference buses.
