Signal Circuit Inspection
- Ignition "OFF".
- Refer to "ETC (ELECTRONIC THROTTLE CONTROL) SYSTEM " and disconnect Throttle Body connector.
- Ignition "ON".
- Measure voltage between Pin No. 5 (TPS2 Signal) terminal of Throttle Body harness connector and chassis ground.
Specification: Approx. 4 V
- Ignition "OFF".
- Disconnect Battery (-) terminal.
- Refer to "ETC (ELECTRONIC THROTTLE CONTROL) SYSTEM " and disconnect Throttle Body connector.
- Measure resistance between Pin No. 5 (TPS2 Signal) terminal of Throttle Body harness connector and chassis ground.
Specification: Infinite (∞) Ω
- Is the measured value within specification?
YES
- Go to "COMPONENT INSPECTION " procedure.
NO
- Repair open or short in signal circuit between Throttle Body and PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
