DTC P0107 [ZY]


DTC P0107	MAP sensor circuit low input
DETECTION CONDITION	• The PCM monitors input voltage from the MAP sensor. If the input voltage is less than 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 in the first drive cycle. • The PENDING CODE is available if the PCM detects the above malfunction condition. • The FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• MAP sensor malfunction • Connector or terminal malfunction • Open circuit in the wiring harness between MAP sensor terminal C and PCM terminal 2AO • Short to ground in the wiring harness between MAP sensor terminal C and PCM terminal 2AO • Short to ground in the wiring harness between MAP sensor terminal B and PCM terminal 2AP • PCM malfunction


STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT MAP SENSOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the MAP 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 8.
3		No	Go to the next step.
4	INSPECT MAP SENSOR CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the following terminals: - MAP sensor terminal C (wiring harness-side) and body ground - MAP 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 8.
4		No	Go to the next step.
5	INSPECT MAP SENSOR • Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [ZY].) • Is there any malfunction?	Yes	Replace the MAP sensor, then go to Step 8.
5		No	Go to the next step.
6	INSPECT PCM FOR POOR CONNECTION • Turn the ignition switch 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 8.
6		No	Go to the next step.
7	INSPECT MAP SENSOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between the following terminals: - MAP sensor terminal C (wiring harness-side) and PCM terminal 2AO (wiring harness-side) • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0107 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Perform the "KOEO or KOER self-test". (See KOEO/KOER SELF TEST [ZY].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (SeePCM REMOVAL/INSTALLATION [ZY].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ZY].)
9		No	DTC troubleshooting completed.
