DTC test: SES light, why? Hello,
I have a SES light. I previously thought it was for my gutted cats, so I turned off the following codes:
P0137 HO2S Circuit Low Voltage Bank 1 Sensor 2
P0138 HO2S Circuit High Voltage Bank 1 Sensor 2
P0140 HO2S Circuit Insufficiency Activity Bank 1 Sensor 2
P0141 HO2S Heater Circuit Bank 1 Sensor 2
P0157 HO2S Circuit Low Voltage Bank 2 Sensor 2
P0158 HO2S Circuit High Voltage Bank 2 Sensor 2
P0160 HO2S Circuit Insufficiency Activity Bank 2 Sensor 2
P0161 HO2S Heater Circuit Bank 2 Sensor 2
P0420 Catalyst System Low Efficiency Bank 1
P0430 Catalyst System Low Efficiency Bank 2
Anyways, I rewrote the program, SES light goes off; all good. Now, the light has come back on. I went and logged and found the following thru a DTC test:
P0405 - Exhaust Gas Recirculation (EGR) Position Sensor Circuit Low Voltage (SES) (Pending) (OLD) (History) (Current) (Immature)
Continuous Tests:
Misfire - Incomplete
Fuel System - Complete
Comprehensive Component - Complete
Once Per Trip Tests:
Catalyst - Incomplete
Heated Catalyst - n/a
Evaporative System - Complete
Secondary Air System - n/a
A/C System Refrigerant - n/a
Oxygen Sensor - Complete
Oxygen Sensor Heater - Complete
EGR System - Complete
My main concern is: P0405 - Exhaust Gas Recirculation (EGR) Position Sensor Circuit Low Voltage (SES) (Pending) (OLD) (History) (Current) (Immature)
Do I have an SES light because of a "Position Sensor Circuit Low Voltage"? If so, how do I fix this problem? If not, what might be the cause of the SES light? I blocked off egr, but I have it turned off in the editor.
Any suggestions?
Thank you,
Kyle
