Monitored & Set Conditions

Circuit is monitored with ignition on and engine running. DTC will be stored in Powertrain Control Module (PCM) memory when knock sensor circuit voltage falls to less than a minimum value at idle or deceleration. The minimum value is from a look-up table internal to PCM and is based on engine speed. The DTC will also set if sensor output is more than 5 volts. Possible causes for DTC to set are: intermittent condition, defective knock sensor, defective PCM, or defective connectors or wiring.
