Check Engine Light
Check Engine Light - Freelander
Hi - I am after some help with a small problem I have with my L series diesel freelander.
The engine is a 4 cylinder diesel with ECU controlled injection pump. The accelerator is fly by wire.
I drove to work OK and at lunch I went to go out and I noticed that on start up, the engine RPM blipped to 1800 then settled back to normal idle of around 850. As the engine revs came back down to idle the 'check engine' light came on. I switched off and went back through the startup routine - on turning on the ignition all the lights did the right thing and went out - which indicates the "fault" is not being stored in the ECU - on starting the engine, exactly the same happens - there is initially no check engine light, the engine starts and immediately blips to 1800rpm and when coming back to idle the "check engine" cames on.
The engine runs OK and will happily drive the car around - covered about 60km at lunch - no problems but the check engine light stays on.
My thoughts are that the blip in RPM is not being generated by the ECU (or the check engine light would come on first) but is being generated by something else (such as the accelerator potentiometer) and the blip in revs is being detected by the the ECU and sending a fault message.
Any ideas as my only real option in Canberra to fix is to take it to the stealer which I am not keen on doing.
Thanks
Garry
