P20F3 Trouble Code

View P20F3 obd/2 error code description and symptoms. P20F3 engine photo

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 P20F3 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 P20F3, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code P20F3 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

P20F3 Error Code Repair Process :

The scent may P20F3 signal oil or coolant leaking from their normally closed-loop systems, or it may indicate dangerous exhaust gases invading your car's interior. Car and truck exhaust contains toxic gases such P20F3, so if the inside of your car p20f3 scr nox pre- catalyst efficiency below threshold bank 2 as if you were standing behind your car, get out and get it fixed. Fight the urge to take a little nap first. So sleepy. That's the carbon monoxide talking, friends. At least open a window on your way to the shop.

P20F3 is a kind of Powertrain Trouble Code

Common Causes of P20F3

A common cause of code P20F3 is the failure of P20F3 SCR NOx Pre- Catalyst Efficiency Below Threshold Bank 2, but there are several other possible causes as well, such as ;

Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
Faulty TCM or TCM programming
Exhaust tube
