DTC P0507[LF ATX (FN4A-EL), L3 ATX]

id0102b6808700

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 the brake pedal is depressed (brake switch is on).

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}, the PCM cancels diagnosis of P0507.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the 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 the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Electronic throttle control system 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.
1		No	Record FREEZE FRAME DATA on 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 RELATED PENDING OR STORED DTCS • Turn the ignition switch off, then to the ON position (Engine off). • Verify PENDING CODE or stored DTCs using the M-MDS. • Is other DTC present?	Yes	Repair the applicable DTCs. (See DTC TABLE[LF ATX (FN4A-EL), L3 ATX].)
3		No	Go to the next step.
4	INSPECT VACUUM HOSE CONNECTION • Are vacuum hoses connecting accurately? (See INTAKE AIR SYSTEM MANIFOLD VACUUM INSPECTION[LF, L3].)	Yes	Go to the next step.
4		No	Reconnect vacuum hose accurately, then go to Step 5.
5	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 M-MDS. • Depress the brake pedal for 14 s or more. • Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[LF, L3].)
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE[LF ATX (FN4A-EL), L3 ATX].) • Is there any DTC present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[LF ATX (FN4A-EL), L3 ATX].)
6		No	Troubleshooting completed.
