DTC P0107 [L8, LF, L3]

id0102a1803400

DTC P0107 | MAP sensor circuit low input
--- | ---
DETECTION CONDITION | • The PCM monitors the input voltage from the MAP sensor when intake air temperature is above -10 °C {14 °F}. If the input voltage is below 0.1 V, the PCM determines that the MAP sensor circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • Are any DTCs is stored in the PCM memory.
POSSIBLE CAUSE | • MAP sensor malfunction • Connector or terminal malfunction • Short to ground in wiring harness between MAP sensor terminal D and PCM terminal 2AG • MAP sensor signal circuit and MAP sensor ground circuit are shorted each other • Open circuit in wiring harness between MAP sensor terminal C and PCM terminal 2AU • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY MAP PID WHEN MAP SENSOR CONNECTOR IS DISCONNECTED • Connect the WDS or equivalent to DLC-2. • Access MAP PID. • Disconnect the MAP sensor connector. • Is the voltage above 4.9 V? | Yes | Go to the next step.
No | Go to Step 5.
4 | INSPECT POWER SUPPLY CIRCUIT VOLTAGE AT MAP SENSOR CONNECTOR Note • If DTC P0122 and P2228 are also retrieved with P0107, go to CONSTANT VOLTAGE troubleshooting procedure. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between MAP sensor terminal C (wiring harness-side) and body ground. • Is the voltage within 4.5- 5.5 V? | Yes | Inspect for poor connection at MAP sensor terminal C (wiring harness-side). • Repair or replace the terminal if necessary. • If there is no malfunction, replace the MAP sensor. Then go to Step 7.
No | Inspect for open circuit in the wiring harness between PCM terminal 2AU (wiring harness-side) and MAP sensor terminal C (wiring harness-side). Repair or replace the suspected wiring harness, then go to Step 7.
5 | INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for continuity between MAP sensor terminal D (wiring harness-side) and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness, then go to Step 7.
No | Go to the next step.
6 | INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUIT FOR SHORT EACH OTHER • Inspect for continuity between MAP sensor terminals D and A (wiring harness-side). • Is there continuity? | Yes | Repair or replace the wiring harness, then go to the next step.
No | Go to the next step.
7 | VERIFY TROUBLESHOOTING OF DTC P0107 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position. (Engine off) • Clear the DTC from the memory using the WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L3].)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L8, LF, L3].) • Are any DTC present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [L8, LF, L3].)
No | Troubleshooting completed.
