Parameter Identifier (PID)

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

PID	DESCRIPTION	ACTION
0x0645	Bank 1 Particulate Filter - Exhaust Back Pressure	Feedback values for the gasoline particulate filter pressure sensor (exhaust back pressure) bank 1 With the ignition on, engine not running, check the pressure sensor value, this should be close to 0 (no gas flow) If the sensor is reading above this then the sensor is offset
0x0646	NOTE: Should be in V engine, not in AJ20-P4 Bank 2 Particulate Filter - Exhaust Back Pressure	Feedback values for the gasoline particulate filter pressure sensor (exhaust back pressure) bank 2 With the ignition on, engine not running, check the pressure sensor value, this should be close to 0 (no gas flow) If the sensor is reading above this then the sensor is offset

PID

DESCRIPTION

ACTION

0x0645

Bank 1 Particulate Filter - Exhaust Back Pressure

Feedback values for the gasoline particulate filter pressure sensor (exhaust back pressure) bank 1

With the ignition on, engine not running, check the pressure sensor value, this should be close to 0 (no gas flow)
If the sensor is reading above this then the sensor is offset

0x0646

NOTE: Should be in V engine, not in AJ20-P4

Bank 2 Particulate Filter - Exhaust Back Pressure

Feedback values for the gasoline particulate filter pressure sensor (exhaust back pressure) bank 2

With the ignition on, engine not running, check the pressure sensor value, this should be close to 0 (no gas flow)
If the sensor is reading above this then the sensor is offset
