DTC P0222:00 [MZR-CD (RF Turbo)]

id0102f1702800

DTC P0222:00

Accelerator pedal position (APP) sensor No.2 circuit low input
DETECTION CONDITION
•  The PCM monitors the input signal from the APP sensor No.2. If the voltage from the APP sensor No.2 is less than 1.16 V, the PCM determines that there is a malfunction in the APP sensor No.2 circuit.
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  APP sensor No.2 malfunction
•  Connector or terminal malfunction
•  Open circuit in wiring harness between APP sensor terminal A and PCM terminal 82
•  Short to ground in wiring harness between APP sensor terminal A and PCM terminal 82
•  Open circuit in wiring harness between APP sensor terminal B and PCM terminal 91
•  Short to ground in wiring harness between APP sensor terminal B and PCM terminal 91
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to available Service Information.
•  If vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
•  Connect the M-MDS to the DLC-2.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”.
(See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD (RF Turbo)].)
4
INSPECT APP SENSOR CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the APP sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 9.
No
Go to the next step.
5
INSPECT APP SENSOR NO.2 CIRCUIT FOR SHORT TO GROUND
•  Switch the ignition to off.
•  Inspect for continuity between the following terminals and body ground:
―  APP sensor terminal A (wiring harness-side) and body ground
―  APP sensor terminal B (wiring harness-side) and body ground
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 9.
No
Go to the next step.
6
INSPECT APP SENSOR NO.2
•  Inspect the APP sensor No.2.
•  Is there any malfunction?
Yes
Replace the accelerator pedal, then go to Step 9.
(See ACCELERATOR PEDAL COMPONENT REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No
Go to the next step.
7
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 9.
No
Go to the next step.
8
INSPECT APP SENSOR NO.2 CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  Inspect for continuity between the following terminals:
―  APP sensor terminal A (wiring harness-side) and PCM terminal 82 (wiring harness-side)
―  APP sensor terminal C (wiring harness-side) and PCM terminal 91 (wiring harness-side)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9
VERIFY TROUBLESHOOTING OF DTC P0222:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the Repair Verification Drive Mode.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD (RF Turbo)].)
No
DTC troubleshooting completed.
