Hi, I get the following codes when doing the key trick.

P0418 Secondary air injection (AIR) pump relay A – circuit malfunction Wiring, AIR pump relay, ECM

P0408 Exhaust gas recirculation (ERG) valve position sensor B – high input Wiring short to positive, EGR valve position sensor, ECM
- that sounds like a fault from the ORM

P 1256 - cant find a report for

P0120 Throttle position (TP) sensor A/accelerator pedal position (APP) sensor A – circuit malfunction Wiring,TP/APP sensor, ECM Throttle position (TP) switch A/accelerator pedal position (APP) switch A – circuit malfunction Wiring,TP/APP switch, ECM

P0299 Turbo/super charger – low boost Mechanical fault
So it says but everything runs fine? No obvious power loss.

P 1225 - no info!


Please give any feedback on what could be the problems and possible solutions thanks a mil

Quiksilver,

The key trick most likely does not work on your vehicle with any degree of accuracy.

P0418, P0408, P1256, P0120 and P1225 are not valid codes for a 2006 KJ Liberty CRD. The P0299 is a turbo underboost and is most likely not active, just stored so no depower condition.

You need a real scan tool to better understand what is going on here.
