| STEP | CHECK | YES | NO |
1.CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM.
3) Disconnect the connectors from electronic throttle control.
4) Measure the resistance between ECM connector and chassis ground.
Connector & terminal
(B134) No. 19 — Chassis ground:
(B134) No. 28 — Chassis ground:
(B134) No. 28 — (B137) No. 4:
Is the resistance 1 M? or more?

Repair the ground short circuit of harness between ECM connector and electronic throttle control connector.
2.CHECK SHORT CIRCUIT INSIDE THE ECM.
1) Connect the connector to ECM.
2) Measure the resistance between electronic throttle control connector and engine ground.
Connector & terminal
(E57) No. 4 — Engine ground:
Is the resistance 1 M? or more?
Replace the electronic throttle control. Throttle Body">
Repair the ground short circuit of harness between ECM connector and electronic throttle control connector. Replace the ECM if defective. Engine Control Module (ECM)">
1. OUTLINE OF DIAGNOSIS
Detect the open or short circuit of throttle position sensor 2.
Judge as NG if out of specification.
2. COMPONENT DESCRIPTION
(1) | Throttle position sensor 1 signal | (3) | Throttle position sensor | (4) | Engine control module (ECM) |
(2) | Throttle position sensor 2 signal |
3. EXECUTION CONDITION
Secondary Parameters | Execution condition |
Battery voltage | ≥ 6 V |
4. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously.
5. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Malfunction Criteria | Threshold Value |
Sensor 2 input voltage | ≤ 1.133 V |
Time Needed for Diagnosis: 24 ms
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
