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. MONITORING CONDITIONS ― Calculated load: 13—32 % Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle. • FREEZE FRAME DATA (Mode 2/Mode 12) is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • MAP sensor connector or terminals malfunction • MAP sensor malfunction • Short to ground in wiring harness between MAP sensor terminal C and PCM terminal 2AU • PCM connector or terminals malfunction • Open circuit in wiring harness between MAP sensor terminal C and PCM terminal 2AU • MAP sensor signal circuit and ground circuit are shorted to each other • Short to ground in wiring harness between MAP sensor terminal D and PCM terminal 2AG • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 12) been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2 | VERIFY RELATED SERVICE 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 M-MDS to the DLC-2. • Perform the PID/DATA Monitor and Record Procedure and access the MAP PID. (See ON-BOARD DIAGNOSTIC TEST [L8, LF].) • Disconnect the MAP sensor connector. • Is the voltage above 4.9 V? | Yes | Go to the next step.
No | Go to Step 9.
4 | INSPECT POWER SUPPLY CIRCUIT VOLTAGE AT MAP SENSOR CONNECTOR • MAP sensor connector is disconnected. • 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 | Go to the next step.
No | Go to Step 6.
5 | INSPECT MAP SENSOR CONNECTOR AND TERMINALS • Turn the ignition switch off. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to Step 13.
No | Replace the MAP sensor, then go to Step 13. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [L8, LF].)
6 | INSPECT MAP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND • MAP sensor connector is disconnected. • Turn the ignition switch off. • Inspect for continuity between MAP sensor terminal C (wiring harness-side) and body ground. • Is there continuity? | Yes | If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [L8, LF].) Go to Step 13.
No | Go to the next step.
7 | INSPECT PCM CONNECTOR AND TERMINALS • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to Step 13.
No | Go to the next step.
8 | INSPECT MAP SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • MAP sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor terminal C (wiring harness-side) and PCM terminal 2AU (wiring harness-side). • Is there continuity? | Yes | Go to Step 13.
No | Repair or replace the wiring harness for a possible open circuit, then go to Step 13.
9 | INSPECT MAP SENSOR CONNECTOR AND TERMINALS • Turn the ignition switch off. • Disconnect the MAP sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to Step 13.
No | Go to the next step.
10 | INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • MAP sensor is disconnected. • Inspect for continuity between MAP sensor terminal D (wiring harness-side) and body ground. • Is there continuity? | Yes | If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [L8, LF].) Go to Step 13.
No | Go to the next step.
11 | INSPECT PCM CONNECTOR AND TERMINALS • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to Step 13.
No | Go to the next step.
12 | INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUIT FOR SHORT TO EACH OTHER • MAP sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor terminals D and A (wiring harness-side). • Is there continuity? | Yes | Repair or replace the suspected wiring harness, then go to the next step.
No | Go to the next step.
13 | VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position. (engine off) • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L8, LF].) • Start the engine and warm it up completely. • Perform the KOEO/KOER self test. (See KOEO/KOER SELF TEST [L8, LF].) • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF].)
No | Go to the next step.
14 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF].) • Are any DTCs present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [L8, LF].)
No | DTC troubleshooting completed.
