P069F Throttle Actuator Control Lamp Control Circuit

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P069F concerns the hard-wired control circuit of the electronic throttle warning lamp (called 'reduced power', wrench or EPC lamp depending on the maker), which lights when the throttle control detects a fault and limits power. The module monitors this output electrically for open circuit and shorts; it cannot see whether the lamp lights. No manufacturer document available to us uses P069F – Ford, for example, switches its wrench lamp via the instrument cluster over the bus, not on its own wire. CARB requires output circuits to be monitored. Without a working lamp the driver is not warned when the engine enters throttle limp mode. The MIL circuit is P0650.

Likely causes

Open or short in the lamp wire between engine module and cluster
Lamp/LED or its driver in the instrument cluster faulty
Connector at cluster or module corroded or loose
Engine module driver faulty

Symptoms

  • Throttle warning lamp does not light at bulb check, or stays on
  • No warning when the engine goes into throttle limp mode
  • Code stored, engine runs normally
