P04AB Pontiac Stinger OBD Code

OBD/2 P04AB error code description and symptoms.

EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on.
The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum. Vacuum supply EGR valve stuck closed EGR valve leaks vacuum EGR flow path restricted EGRVR circuit shorted to PWR VREF open to D.P.F. EGR sensor D.P.F. EGR sensor downstream hose off or plugged EGRVR circuit open to PCM VPWR open to EGRVR solenoid D.P.F. EGR sensor hoses both off D.P.F. EGR sensor hoses reversed Damaged EGR orifice tube Damaged EGRVR solenoid Damaged PCM Perform KOER self-test and look for DTC P04AB as an indication of a hard fault.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P04AB, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code P04AB on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

P04AB Pontiac Stinger Error Code Repair Process :

If your catalyst temperature sensor failure check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system P04AB and engine control unit are in charge of monitoring a bunch of different catalyst temperature sensor failure, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Pontiac Stinger P04AB OBD2 Code

A common cause of code P04AB is the failure of Catalyst Temperature Sensor Failure, but there are several other possible causes as well, such as ;

Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
1Camshaft Position Sensor circuit poor electrical connection
Oil flow restriction in the oil passages or the VCT valve body

P04AB is a kind of Powertrain Trouble Code

Powertrain of a modern automobile, comprising engine (with exhaust system), transmission, drive shaft, suspension and the wheels. In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.
