DTC P2229[MTX, LF ATX (FS5A-EL)]

id0102b4813000

DTC P2229

BARO sensor circuit high input

DETECTION CONDITION

•  PCM monitors the input voltage from the BARO sensor. If the input voltage at the PCM is above 4.45 V, the PCM determines that the BARO sensor circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

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

•  FREEZE FRAME DATA is available.

•  DTCs are stored in the PCM memory.

POSSIBLE CAUSE

•  BARO sensor malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME 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 the 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	INSPECT BARO SENSOR MALFUNCTION • Start the engine. • Access the BARO PID using the M-MDS. • Inspect that the BARO PID is within the specification. • Is there any malfunction?	Yes	Replace the PCM, then go to the next step.
3		No	Go to the next step.
4	VERIFY TROUBLESHOOTING OF DTC P2229 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the memory using the M-MDS. • Start engine and warm it up completely. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[LF, L3].)
4		No	No concern is detected. Go to the next step.
5	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[MTX, LF ATX (FS5A-EL)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[MTX, LF ATX (FS5A-EL)].)
5		No	Troubleshooting completed.
