P245211, P245E11

DTC Code	DTC Name
P245211	Particulate Filter Pressure Sensor "A" Circuit Short to Ground
P245E11	Particulate Filter Pressure Sensor "B" Circuit Short to Ground

DESCRIPTION

A differential pressure sensor is installed to monitor the pressure before the GPF (Gasoline Particulate Filter) catalyst converter. The sensor is a semiconductor type that is not affected by the exhaust gas. The differential pressure sensor outputs the difference between the atmospheric pressure and the pressure before the GPF catalyst.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P245211	Particulate Filter Pressure Sensor "A" Circuit Short to Ground	The output voltage from the differential pressure sensor (bank 1) is below 0.4 V for 3 seconds or more (1 trip detection logic).	Open or short in differential pressure sensor (bank 1) circuit Differential pressure sensor (bank 1) ECM	-	DTC stored	SAE: P2454
P245E11	Particulate Filter Pressure Sensor "B" Circuit Short to Ground	The output voltage from the differential pressure sensor (bank 2) is below 0.4 V for 3 seconds or more (1 trip detection logic).	Open or short in differential pressure sensor (bank 2) circuit Differential pressure sensor (bank 2) ECM	-	DTC stored	SAE: P2460

Tech Tips

When a DTC is output, check the Data List item "GPF Differential Pressure Sensor Bank 1 and GPF Differential Pressure Sensor Bank 2" using the GTS.

DTC No.	GPF Differential Pressure Sensor Bank 1 or GPF Differential Pressure Sensor Bank 2	Malfunction
P245211	Approximately -5 kPa [-0.73 psi]	Short in PEX circuit to ground Short in PEX circuit to EPR circuit Open in VCPP circuit
P245E11	Approximately -5 kPa [-0.73 psi]	Short in PEX2 circuit to ground Short in PEX2 circuit to EPPM circuit Open in VCPP circuit

If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION

In order to detect abnormality in the differential pressure sensor, the ECM always monitors the output voltage from the sensor. When the sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the sensor circuit and illuminates the MIL.

Example:

When the sensor output voltage is below 0.4 V for 3 seconds or more, the ECM stores a DTC.

MONITOR STRATEGY

Frequency of Operation

Continuous

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the engine switch on (IG) and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG).
Turn the GTS on.
Start the engine and wait 5 seconds or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the pending DTCs.
Tech Tips
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P245211 or P245E11.

Check the DTC judgment result.

GTS Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions

Tech Tips

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.

Tech Tips

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Bank 1 refers to the bank that includes the No. 1 cylinder*.

*: The No. 1 cylinder is the cylinder which is farthest from the transmission.

Bank 2 refers to the bank that does not include the No. 1 cylinder.

P245E11	Bank 2

PROCEDURE

CHECK HARNESS AND CONNECTOR

Tech Tips

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

Disconnect the differential pressure sensor connector.
Turn the engine switch on (IG).

Measure the voltage according to the value(s) in the table below.

Standard Voltage

Tester Connection	Condition	Specified Condition
D63-3 (VCDR) - D63-1 (E2R)	Engine switch on (IG)	4.5 to 5.5 V
D64-3 (VCDL) - D64-1 (E2L)	Engine switch on (IG)	4.5 to 5.5 V
D63-2 (VPR) - D63-1 (E2R)	Engine switch on (IG)	3.0 to 5.5 V
D64-2 (VPL) - D64-1 (E2L)	Engine switch on (IG)	3.0 to 5.5 V

Turn the engine switch off and wait for at least 30 seconds.

Measure the resistance according to the value(s) in the table below.

Standard Resistance

Tester Connection	Condition	Specified Condition
D63-3 (VCDR) - D63-2 (VPR)	Engine switch off	171 to 189 kΩ
D64-3 (VCDL) - D64-2 (VPL)	Engine switch off	171 to 189 kΩ
