DTC P2145 [AJ]

BME010202100W08

DTC P2145

EGR boost sensor solenoid valve circuit high input

DETECTION CONDITION

• The PCM monitors the EGR boost sensor solenoid valve control signal. If PCM turns the EGR boost sensor solenoid valve off but voltage still remains high, the PCM determines that the EGR boost sensor solenoid valve circuit has malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.

POSSIBLE CAUSE

• EGR boost sensor solenoid valve malfunction
• Connector or terminal malfunction
• Short to power supply in wiring between EGR boost sensor solenoid valve terminal B and PCM terminal 93
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Check for related Service Information and/or on-line 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.
No
Go to the next step.
2
CLASSIFY INTERMITTENT CONCERN OR CONTINUOUS CONCERN
• Turn the ignition switch off then to the ON position (Engine off).
• Is same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists. Go to INTERMITTENT CONCERNS TROUBLESHOOTING procedure.
3
INSPECT POOR CONNECTION OF EGR BOOST SENSOR SOLENOID VALVE CONNECTOR
• Turn the ignition switch off.
• Check for poor connection (damaged, pulled-out pins, corrosion, etc.).
• Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 7.
No
Go to the next step.
4
INSPECT EGR BOOST SENSOR SOLENOID VALVE CIRCUIT FOR SHORT TO POWER SUPPLY
• Disconnect EGR boost sensor solenoid valve connector.
• Turn the ignition switch to the ON position (Engine off).
• Measure the voltage between EGR boost sensor solenoid valve terminal B (harness-side) and body ground.
• Is the voltage B+?
Yes
Repair or replace harness, then go to Step 7.
No
Go to the next step.
5
INSPECT EGR BOOST SENSOR SOLENOID VALVE
• Inspect the EGR boost sensor solenoid valve.
• Is the EGR boost sensor solenoid valve normal?
Yes
Go to the next step.
No
Replace EGR boost sensor solenoid valve, then go to Step 7.
6
INSPECT POOR CONNECTION OF PCM CONNECTOR
• Turn the ignition switch off.
• Disconnect PCM connector.
• Check for poor connection (damaged, pulled-out pins, corrosion, etc.).
• Is there any malfunction?
Yes
Repair terminal, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING OF DTC P2145 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Turn the ignition switch off then to the ON position (Engine off).
• Is same DTC present?
Yes
Replace PCM, then go to the next step.
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.
No
Troubleshooting completed.
