DTC P0069

MAP sensor and BARO sensor signal plausibility error

DETECTION CONDITION

•  The PCM monitors the MAP sensor and BARO sensor signals. If the following conditions are detected, the PCM determines that the MAP sensor and BARO sensor signals have a plausibility error.

―  Difference between MAP and BARO sensors is 15 MPa {153 kgf/cm², 2176 psi} or more for continuous 10 s

―  Difference between MAP and BARO sensors is 40 MPa {408 kgf/cm², 5802 psi} or more for continuous 10 s when regenerating diesel particulate filter

POSSIBLE CAUSE

•  MAP sensor malfunction

•  BARO sensor (built-into 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 the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is P0237, P0238 P2227, P2228 or P2229 on FREEZE FRAME DATA?	Yes	Go to the applicable DTC inspection. (See DTC P0237 [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See DTC P0238 [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See DTC P2227 [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See DTC P2228 [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See DTC P2229 [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
3		No	Go to the next step.
4	CLASSIFY MALFUNCTION AS MAP SENSOR OR ATMOSPHERIC PRESSURE SENSOR MALFUNCTION • Connect the M-MDS to DLC. • Access BARO and MAP PIDs. • Switch the ignition to ON (Engine off). • Compare the barometer with each PID. • Do the PID indications equal the barometer indication?	Yes	Go to Step 6.
4		No	If the MAP PID is not equal to the barometer"s indication: Go to the next step. If the BARO PID is not equal to the barometer"s indication: Replace the PCM, then go to Step 6
5	INSPECT MAP SENSOR • Perform MAP sensor inspection. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [MZ-CD 1.6 (Y6) (EURO4 emission level)].) • Is MAP sensor normal?	Yes	Go to the next step.
5		No	Replace MAP sensor, then go to the next step. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
6	VERIFY THAT DTC P0069 TROUBLESHOOTING IS COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Run the vehicle under the FREEZE FRAME DATA stored condition. • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6) (EURO4 emission level)].) Go to the next step.
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the after repair procedure. (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6) (EURO4 emission level)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
7		No	DTC troubleshooting completed.
