DTC P0507 [L3]

BME010200500W04

DTC P0507 | Idle control system RPM higher than expected
--- | ---
DETECTION CONDITION | • Actual idle speed is lower 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 less than 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).
• MIL illuminates if PCM detects the above malfunction conditions 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 PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in PCM memory.
POSSIBLE CAUSE | • IAC valve malfunction • Accelerator cable misadjusted • Actuator cable misadjusted • 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 next step.
No | Record FREEZE FRAME DATA on repair order, then go to 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 next step.
No | Go to next step.
3 | VERIFY RELATED PENDING OR STORED DTCS • Turn ignition key to OFF, then ON (Engine OFF). • Verify pending code or stored DTCs using WDS or equivalent. • Is other DTC present? | Yes | Repair applicable DTCs. (See DTC TABLE [L3].)
No | Go to next step.
4 | INSPECT IAC VALVE MALFUNCTION • Perform IAC valve inspection. (See IDLE AIR CONTROL (IAC) VALVE INSPECTION [L3].) • Is IAC valve okay? | Yes | Go to next step.
No | Replace IAC valve, then go to Step 9.
5 | INSPECT ACCELERATOR CABLE FREE PLAY • Turn ignition key to OFF. • Is accelerator cable free play okay? (See ACCELERATOR CABLE INSPECTION [L3].) | Yes | Go to next step.
No | Adjust accelerator cable free play, then go to Step 9. (See ACCELERATOR CABLE INSPECTION [L3].)
6 | INSPECT ACTUATOR CABLE FREE PLAY • Is actuator cable adjustment okay? | Yes | Go to next step.
No | Adjust actuator cable free play, then go to Step 9.
7 | INSPECT VACUUM HOSE CONNECTION • Are vacuum hoses connected accurately? (See INTAKE-AIR SYSTEM HOSE ROUTING DIAGRAM [L3].) | Yes | Go to next step.
No | Reconnect vacuum hose accurately, then go to step 9.
8 | VISUAL INSPECT THROTTLE VALVE • Remove throttle body. • Is throttle valve fully closed? | Yes | Go to next step.
No | Clean or replace throttle body, then go to next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0507 COMPLETED • Make sure to reconnect all disconnected connectors. • Start engine. • Clear DTC from PCM memory using WDS or equivalent. • Depress brake pedal for 14 s or more.
• Is PENDING CODE of same DTC present?
Yes
Replace PCM, then go to next step.
(See PCM REMOVAL/INSTALLATION [L3].)
No | Go to next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3].) • Is there any DTC present? | Yes | Go to applicable DTC troubleshooting. (See DTC TABLE [L3].)
No | Troubleshooting completed.
