DTC P2229:00 [MZR-CD 2.2]

DTC P2229:00	BARO sensor circuit high input
DETECTION CONDITION	• The PCM monitors the input signal for the barometric pressure. If the voltage from the barometric pressure sensor is more than 4.7 V, the PCM determines that there is a malfunction in the barometric pressure sensor signal system. Monitoring condition • Battery voltage: 8—20 V Diagnostic support note • The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA (mode2) and snapshot data are available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• BARO sensor (integrated in PCM) malfunction

DTC P2229:00

BARO sensor circuit high input

DETECTION CONDITION

• The PCM monitors the input signal for the barometric pressure. If the voltage from the barometric pressure sensor is more than 4.7 V, the PCM determines that there is a malfunction in the barometric pressure sensor signal system.

Monitoring condition

• Battery voltage: 8—20 V

Diagnostic support note

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

• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.

• FREEZE FRAME DATA (mode2) and snapshot data are available.

• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• BARO sensor (integrated in PCM) malfunction

STEP	INSPECTION	ACTION
1	VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED • Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?	Yes	Go to the next step.
No	Record the FREEZE FRAME DATA (mode2) and snapshot 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 repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No	Go to the next step.
3	VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Go to the next step.
No	Intermittent concern exists. Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
4	VERIFY TROUBLESHOOTING OF DTC P2229:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)
No	No concern is detected. Go to the next step.
5	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD 2.2].)
No	DTC troubleshooting completed.
