DTC P245B:00 [MZ-CD 1.6]

DTC P245B:00	EGR cooler bypass valve solenoid valve control circuit range/performance problem
DETECTION CONDITION	• The PCM monitors the EGR cooler bypass valve solenoid valve signal voltage. PCM detects the following conditions, the PCM determines that the EGR cooler bypass valve solenoid valve circuit has a malfunction. ― Input voltage is 0.5 V or more and 0.7001 V or less ― Input voltage exceeds 2 V and is less than 3.5001 V ― Input voltage exceeds 4.7 V and is 4.8 V or more
POSSIBLE CAUSE	• EGR cooler bypass valve solenoid valve malfunction • PCM malfunction

• PCM malfunction

STEP	INSPECTION	ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED 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.
No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND/OR DTC • Switch the ignition to ON (engine off). • Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [MZ-CD 1.6].) • Is the other PENDING CODE/DTC also present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZ-CD 1.6].)
No	Go to the next step.
4	INSPECT EGR COOLER BYPASS VALVE SOLENOID VALVE • Inspect the EGR cooler bypass valve solenoid valve. • Is there any malfunction?	Yes	Replace the EGR cooler bypass valve solenoid valve, then go to the next step.
No	Go to the next step.
5	VERIFY THAT DTC P245B:00 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].) Go to the next step.
No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform the after repair procedure. (See AFTER REPAIR PROCEDURE [MZ-CD 1.6].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZ-CD 1.6].)
No	DTC troubleshooting completed.
