Peugeot Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is XXXXX XXXXX I will try help you with this.
Does the engine start ok when it is cold?
No starting problems at all
Do you have access to a scan tool?
Did it get new sparkplugs, air filter and fuel filter at the service?
yes, plugs and filters changed but the problem remained.
Including fuel filter?
That I would have to check, I was assured all filters were done
Was the air mass meter and o2 sensor replaced for this fault?
The air mass meter was but that was the only one that was changed
You said the lambda was changed also?
Lambda is o2
sorry, different terminology.
o2 easier to type.
So was o2 also changed for this fault?
there was a code on the diagnostics that indicated the o2 sensor was faulty so in an attempt to cure the fault this was also changed.
no further fault codes recorded though
Do you know what the code number was?
I would say most likely cause is the engine temperature sensor but first make sure the fuel filter was replaced at the service.
sounds like a plan. I will giver the garage a call tmrw and see what actual filters they changed
thanks for your help
The sensor can be checked with the scan tool.
Make sure the reading from it matches the actual engine temperature, especially as the engine is heating up.
I will pass on the advice, it's been frustrating
I suspect it could be reading hotter than normal which cuts the fuel back a bit. Not so much a problem with a hot engine but limits power when the engine is cold.
Sounds viable and well worth a go
If the sensor is reading a plausible value it wont set a fault code.
but in essence it could be malfunctioning?
OK, I will pass it all on and make sure they check the engine temp sensor, its a very good lead.
Hope it helps.
Please remember to rate my assistance.
Cheers, XXXXX XXXXX way forward and if it doesn't cure the fault as least it's been eliminated.
