DTC P0507 [AJ]

BME010200500204

DTC P0507 | Idle control system RPM higher than expected
--- | ---
DETECTION CONDITION | • Actual idle speed is higher than expected by 200 rpm for 14 s, when brake pedal is depressed (brake switch is ON) and steering wheel is held straight ahead (power steering pressure switch is OFF).

  Note

  • If atmospheric pressure is below 72.3 kPa {542 mmHg, 21.3 inHg} or intake air temperature is below -10 °C {14 °F}, PCM cancels diagnosis of P0507.

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 PCM memory.
POSSIBLE CAUSE | • IAC valve malfunction • Accelerator cable misadjusting • Actuator cable misadjusting • Throttle valve malfunction • Vacuum hose misconnection
• PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record FREEZE FRAME DATA on repair order, then go to the next step.
2 | VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY RELATED PENDING OR STORED DTCS • Turn the ignition switch off, then to the ON position (Engine off). • Verify pending code or stored DTCs using WDS or equivalent. • Is other DTC present? | Yes | Repair applicable DTCs. (See DTC TABLE [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).) (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
No | Go to the next step.
4 | INSPECT IAC VALVE MALFUNCTION • Perform IAC valve inspection. (See IDLE AIR CONTROL (IAC) VALVE INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).) (See IDLE AIR CONTROL (IAC) VALVE INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
• Is the IAC valve normal?
Yes
Go to the next step.
No | Replace the IAC valve, then go to Step 9.
5 | INSPECT ACCELERATOR CABLE FREE PLAY • Turn the ignition switch off. • Is accelerator cable free play normal? (See ACCELERATOR CABLE INSPECTION [AJ].) | Yes | Go to the next step.
No | Adjust accelerator cable free play, then go to Step 9. (See Free Play Inspection.)
6 | INSPECT ACTUATOR CABLE FREE PLAY • Is actuator cable adjustments normal? | Yes | Go to the next step.
No | Adjust actuator cable free play, then go to Step 9.
7 | INSPECT VACUUM HOSE CONNECTION • Are vacuum hoses connecting accurately? | Yes | Go to the next step.
No | Reconnect vacuum hose accurately, then go to step 9.
8 | VISUAL INSPECT THROTTLE VALVE • Remove throttle body. • Is the throttle valve fully closed? | Yes | Go to the next step.
No | Clean or replace the throttle body, then go to the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0507 COMPLETED • Make sure to reconnect all disconnected connectors. • Start the engine. • Clear the DTC from the PCM memory using the WDS or equivalent. • Depress brake pedal for 14.1 s or above.
• Is the PENDING CODE of same DTC present?
Yes
Replace the PCM, then go to the next step.
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [AJ].) • Is there any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).) (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
No | Troubleshooting completed.
