Car Forum / Subaru Cars / July 2006'05 Forester Code P0131
In damp/rainy weather my car had difficulty starting and ended up with the check engine light on/cruise automatically disabled. Subaru rec replacing the A/F & O2 sensor relay. But dealer later said they didn't replace the O2 relay because the code for it wasn't tripped 5 months later after car was sitting in parking lot for several days and it was raining, the car had difficulty starting and the symptoms are the same as before. I haven't brought it in to check if the diag code is the same one My question... I don't want them just to replace the A/F sensor without finding the cause of the problem. Any ideas out there about a sensor problem associated with damp/rainy weather -- mycyberinfo > In damp/rainy weather my car had difficulty starting and ended up with the check engine light on/cruise automatically disabled.

Any ideas out there about a sensor problem associated with damp/rainy weather? Seems to me its possible there is a high voltage problem somewhere. Does it crank and not start? Try to start but sputter? Anyway, if you suspect the code is something different this time, you could try having Autozone read it.

Any ideas out there about a sensor problem associated with damp/rainy weather? The A/F sensor does not affect starting. The ECU does not use the signal from that sensor until the engine has been running for a while and is up to operating temperature. So the code may be from a bad sensor but the starting issue is not. Damp weather starting problems are typically electrical, often from a problem with the wires/coils. thanks for both of your replies. Before the check light came on both times in the damp/rainy weather the car was difficult to start. It sputtered and chugged, then ended up with the check engine light on and the car stayed on chugging for a bit then settled into what I have now, a car that starts OK but runs a bit rough. So my A/F minimum is definetely a current problem, AND I'll have the dealer check the electrical system Thanks -- mycyberinfo |
