Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** usually means idle relearn needs to be done, here is procedure. Let me know if you have more questions, thanks.
I'll open question back up to see if someone else has some ideas. If you weren't getting code before cleaning throttle body then relearn should help, if not I'll see if someone else can shed some light on situation. Someone will reply automatically when they can help. Thanks.
My experience of P2279 is that the ecu is determining that more air is entering the engine than is passing the mass air flow sensor.
I agree with your theory of checking the egr valve as this is high on the list, I would also consider checking the mass air flow sensor as this is providing the readings the ecu is calculating from.
I will have access to the data programs when I get to the office, it's 0820 am here at the moment, I will look up the manufacture's diagnostic chart and come back to you shortly.
Made a call, someone is already in.
It would appear that you need to check the camshaft timing, I include the manufacture's diagnostics procedure.
I hope this helps you resolve the issue, please rate five stars ;)
Let me know if you want the timing information.
Do you have access to the Honda Diagnostic System or are you using a alternate scanner?
The procedure I sent you is from Honda/Acura - I would follow it exactly, paying attention to the air leaks, a hand held mitty vac or similar would be useful.
If their own procedure leads you to the camshaft timing, then I would follow it up, I've worked through the diagnostic procedures many times at the uk factory and they are usually spot on with only the odd exception.
Camshaft timing is likely to be a big job, I would fully follow the diagnostics procedure first, it is the same as they will have access to most likely.
I fear that if the timing is out, it may be time for a new timing belt set.
Good luck, please do let me know how it goes.
If you would consider rating, this does not close the thread and you are welcome to come back to me.
The procedures I've sent you are what the dealer would use, if followed, they will be right.
I only get credit towards my time and research if rated.
