| STEP | CHECK | YES | NO |
1.CHECK HARNESS BETWEEN ECM AND ACCELERATOR PEDAL POSITION SENSOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM.
3) Disconnect the connector from the accelerator pedal position sensor.
4) Measure the resistance between ECM connector and chassis ground.
Connector & terminal
(B135) No. 21 — Chassis ground:
(B135) No. 23 — Chassis ground:
(B135) No. 23 — (B137) No. 4:
Is the resistance 1 M? or more?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2122 THROTTLE/PEDAL POSITION SENSOR/SWITCH "D" CIRCUIT LOW">Go to Step 2.
Repair the short circuit to ground in harness between ECM connector and accelerator pedal position sensor connector.
2.CHECK SHORT CIRCUIT INSIDE THE ECM.
1) Connect the connector to ECM.
2) Measure the resistance between accelerator pedal position sensor connector and chassis ground.
Connector & terminal
(B315) No. 6 — Chassis ground:
Is the resistance 1 M? or more?
Replace the accelerator pedal. Accelerator Pedal">
Repair the short circuit to ground in harness between ECM connector and accelerator pedal position sensor connector. Replace the ECM if defective. Engine Control Module (ECM)">
1. OUTLINE OF DIAGNOSIS
Detect the open or short circuit of accelerator pedal position sensor 1.
Judge as NG if out of specification.
2. COMPONENT DESCRIPTION
(1) | Engine control module (ECM) | (3) | Accelerator pedal position sensor 2 signal | (4) | Accelerator pedal position sensor |
(2) | Accelerator pedal position sensor 1 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 1 input voltage | < 0.298 V |
Time Needed for Diagnosis: 100 ms
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.

Fastening the seatbelt
WARNING
Never use a belt that is twisted or
reversed. In an accident, this can
increase the risk or severity of
injury.
Keep the lap belt as low as
possible on your hips. In a collision,
this spreads the force of the
lap belt over stronger hip bones
instead of across the weaker

Temporary spare tire
WARNING
Never tow a trailer when the
temporary spare tire is used.
The temporary spare tire is not
designed to sustain the towing
load. Use of the temporary spare
tire when towing can result in
failure of the spare tire and/or
less stability of the vehicle and
may lead to an ac ...
