DTC P1411 EGR Valve Position Sensor Circuit Range Problem

CIRCUIT DESCRIPTION
The EGR valve position sensor is mounted on the EGR valve and detects the lift amount of EGR valve. The lift amount of EGR valve which is detected by the EGR valve position sensor provides feedback to the ECM to control the lift amount of EGR valve in response to engine operating conditions.





DETECTING CONDITION

Step 1:

INSPECTION PROCEDURE

HINT: Read freeze frame data using LEXUS hand-held tester or OBD II scan tool. Because freeze frame records the engine conditions when the malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine warmed up or not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.
