What Does P1411 Mean?
The EGR valve position sensor signal is out of expected range or not performing as expected during operation. The sensor readings do not correlate properly with commanded valve position.
Common Causes
30%
EGR position sensor out of calibration or drifting
30%
Carbon buildup causing EGR valve to bind or move sluggishly
25%
EGR valve position sensor failure
10%
Wiring harness high resistance or intermittent connection
5%
EGR valve actuator motor failure or binding
Diagnostic Steps
1
Step 1: Monitor EGR position sensor readings in live data at idle and during acceleration
2
Step 2: Command EGR valve open/closed using scan tool and verify smooth position sensor response
3
Step 3: Remove EGR valve and check for carbon buildup causing binding or restricted movement
4
Step 4: Test position sensor voltage sweep through full valve travel range
5
Step 5: Clean EGR valve thoroughly or replace if position sensor shows erratic or limited range
Estimated Repair Cost
$200 - $600
Parts + labor, varies by vehicle and location
The EGR valve position sensor signal is out of expected range or not performing as expected during operation. The sensor readings do not correlate properly with commanded valve position.
The most common cause of P1411 (EGR Valve Position Sensor Circuit Range/Performance Malfunction) is: EGR position sensor out of calibration or drifting
Typical repair costs for P1411 range from $200 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but may experience performance issues, increased emissions, and potential engine pinging. Repair within two weeks.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1411 to identify the root cause.
