DTC P0107


DTC P0107	MAP sensor circuit low input
DETECTION CONDITION	• The PCM monitors input voltage from the MAP sensor. If the input voltage at PCM terminal 2S 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 2W • Short to ground in the wiring harness between MAP sensor terminal C and PCM terminal 2W • Open circuit in the wiring harness between MAP sensor terminal B and PCM terminal 2S • Short to ground in the wiring harness between MAP sensor terminal B and PCM terminal 2S • PCM malfunction


STEP	INSPECTION		ACTION
1	PERFORM DTC CONFIRMATION PROCEDURE • Perform the DTC CONFIRMATION PROCEDURE. • Is the same DTC present?	Yes	Go to the next step.
1		No	Intermittent concern exists. Go to the INTERMITTENT CONCERN TROUBLESHOOTING procedure.
2	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 7.
2		No	Go to the next step.
3	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 7.
3		No	Go to the next step.
4	INSPECT MAP SENSOR • Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [WITH WU-TWC].) • Is there any malfunction?	Yes	Replace the MAP sensor, then go to Step 7.
4		No	Go to the next step.
5	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 7.
5		No	Go to the next step.
6	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 2W (wiring harness-side) - MAP sensor terminal B (wiring harness-side) and PCM terminal 2S (wiring harness-side) • Is there continuity?	Yes	Go to the next step.
6		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
7	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. • Start the engine. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step.
7		No	Go to the next step.
8	VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC table (With WU-TWC).)
8		No	DTC troubleshooting completed.
