P1224

E : THROTTLE CONTROL POSITION ERROR: P1224

NOTE: For further diagnosis on this DTC, Electronic Engine Controls

E1 : CHECK THROTTLE CONTROL - CIRCUIT FOR CONTINUITY
1. Disconnect the throttle motor electrical connector, PI018.
2. Disconnect the PCM electrical connector, PI001.
3. Measure the resistance between PI001, pin 106 (RW) and throttle motor electrical connector PI018, pin 002 (RW)

Is the resistance less than 5 ohms?

Yes
Goto E2

No
REPAIR the circuit between PCM electrical connector PI001, pin 106 (RW) and throttle motor electrical connector PI018, pin 002 (RW) For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

E2 : CHECK THROTTLE CONTROL + CIRCUIT FOR CONTINUITY
1. Measure the resistance between PCM electrical connector PI001, pin 080 (GW) and throttle motor electrical connector PI018, pin 001 (GW)

Is the resistance less than 5 ohms?

Yes
INSTALL a new PCM. CLEAR the DTC. TEST the system for normal operation.

No
REPAIR the circuit between PCM electrical connector PI001, pin 080 (GW) and throttle motor electrical connector PI018, pin 001 (GW) For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
