Hello All,
So today i stop by the gas station, not to pump gas in to my car but to wash it down with the self wash machine. So i spray my car all over. Once i start my car the CEL came on. I went to my friend who has an ODBII machine.
The error code were
PO174-SYSTEM TOO LEAN
PO171-SYSTEM TOO LEAN

ANY IDEA WHY THIS HAPPENED?

 

hard to tell without freeze frame data, id like to see the STFT and LTFT's as well as map sensor data, compared to baro sensor..

could be just a coincidence..

 

Sorry I can't help you with this but was it the self wash machine at the Gulf gas station on NHP road?

 

yes it was. but i'm still trying to figure out why?

 

something got wet that wasnt supposed to !
pull fuse 12 in the passenger footwell- number may be different on your year, but look for CLOCK- that is the secret backup power for the ECU
Or if you know the radio-nav security codes- disconnect the neg battery cable for a minute then replace- that forces a computer reset- then drive and see if CEL gone

 

there is a note about this in the april acura news. They are claiming it is due to CAI's and if they get a car with those codes and a CAI is installed, to give it back to the customer and tell them that it is due to the CAI.

 

i do have a CAI
