DTC P0107:00 [MZR-CD 2.2]

id0102f3701100

DTC P0107:00

Boost sensor circuit low input

DETECTION CONDITION

•  The PCM monitors the input signal from the boost sensor. If the voltage from the boost sensor is less than 0.33 V, the PCM determines that there is a malfunction in the boost sensor circuit.

Monitoring conditions

―  Following conditions are met:

•  Battery voltage: 8—20 V

•  Intake shutter valve position: more than 8 °

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 (mode2) and snapshot data are available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Boost sensor connector or terminal malfunction

•  Short to ground in wiring harness between boost sensor terminal C and PCM terminal 1CL

•  Short to ground in wiring harness between boost sensor terminal B and PCM terminal 1AY

•  Boost sensor malfunction

•  PCM connector or terminal malfunction

•  Open circuit in the wiring harness between boost sensor terminal C and PCM terminal 1CL

•  PCM malfunction

DTC P0107:00	Boost sensor circuit low input
DETECTION CONDITION	• The PCM monitors the input signal from the boost sensor. If the voltage from the boost sensor is less than 0.33 V, the PCM determines that there is a malfunction in the boost sensor circuit. Monitoring conditions ― Following conditions are met: • Battery voltage: 8—20 V • Intake shutter valve position: more than 8 ° 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 (mode2) and snapshot data are available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Boost sensor connector or terminal malfunction • Short to ground in wiring harness between boost sensor terminal C and PCM terminal 1CL • Short to ground in wiring harness between boost sensor terminal B and PCM terminal 1AY • Boost sensor malfunction • PCM connector or terminal malfunction • Open circuit in the wiring harness between boost sensor terminal C and PCM terminal 1CL • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED • Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (mode2) and snapshot data 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.
2		No	Go to the next step.
3	VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Go to the next step.
3		No	Intermittent concern exists. Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
4	INSPECT BOOST SENSOR CONNECTOR FOR POOR CONNECTION • Switch the ignition to off. • Disconnect the boost 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.
4		No	Go to the next step.
5	INSPECT BOOST SENSOR CIRCUIT FOR SHORT TO GROUND • Switch the ignition to off. • Inspect for continuity between the following terminals and body ground: ― Boost sensor terminal C (wiring harness-side) ― Boost sensor terminal B (wiring harness-side) • 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 the PCM internal circuit). (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) Go to Step 9.
5		No	Go to the next step.
6	INSPECT BOOST SENSOR • Inspect the boost sensor. (See BOOST SENSOR INSPECTION [MZR-CD 2.2].) • Is there any malfunction?	Yes	Replace the boost sensor, then go to Step 9. (See COMMON RAIL REMOVAL/INSTALLATION [MZR-CD 2.2].)
6		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.
7		No	Go to the next step.
8	INSPECT BOOST SENSOR CIRCUIT FOR OPEN CIRCUIT • Switch the ignition to off. • Inspect for continuity between the boost sensor terminal C and PCM terminal 1CL • Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness for possible open circuit, then go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P0107:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) Go to the next step.
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD 2.2].)
10		No	DTC troubleshooting completed.
