Code P0654 and P1276

Ok, so having followed the advice from the forum on obtaining the error codes for my 2005 Jeep (Cherokee in the UK) I have found the following codes come up

P0654 Engine RPM Output Circuit Malfunction
P1276 Accelerator Pedal Position Sensor 1 Circuit Performance

So as a total noob can someone please tell me what I am looking at - is this something to worry about - please bear in mind that as a mere female I will probably have to take this to a local garage if it needs sorting.

Many thanks

Yeah your going to have someone look at it unless you have the correct scan tool to access that data.

As the CRD was not available in the US until "05", the info found - P1276 pointed to a glow plug issue. The P1684 was stated that the PCM memory has been cleared out or that no trouble code was present at the time of scan. Very little help, I know.

In the UK the car is badged as a Cherokee but it seems that if I want any info I have to look at the US Liberty

Thanks, I've also done some research, the P1276 seems to relate to a sensor on the transmission (automatic). As I had an issue with the transmission last year which required replacement and is still under warranty I shall see if this is covered by this warranty.

Unfortunately the other code is P0654 not P1684 and relates to the accelerator pedal sensor. I am hoping that this will also relate to the transmission replacement.

I love this car but it just seems one expensive thing after another goes wrong

Sorry I got the numbers the wrong way round, this is the correct information

OK Peeps I took the car into the garage that did the replacement transmission last year.

They have checked it over and replaced the RPM sensor - the check engine light is no longer on and the car runs smoother.

Now the shock it came to a total of 36 - $60 for you in the USA and that included tax.

The stealership quoted a lot more than that for just checking the codes, without the part and labour.

I love a friendly no nonsense garage mechanic

Glad to hear things are working and no more lights ! That was a decent price for the sensor installed.
