Just bought a 95 Sentra with 90,000 miles from a private owner and Check Engine Light came on the next day. The car runs fine, no problem with idle, but the code came up is,
***OK TO DRIVE***
P0505 - IACV-AAC valve malfunction
P0136 - Oxygen Sensor - IS2
I had the code reset as of now, it again came today and I took off the battery fuse to reset the comp again. But looks like I have to fix the problem. However, I see no symptom of IAC malfunction. Being an XE, this car ain't got no RPM meter, so can't tell whats the idle RPM, but it just feels normal. And as far as the O2 sensor goes, I am getting around 30 mpg in city...don't know what can be wrong with the O2 sensor in that case.. No abnormal smell.. nothing!
Can anyone help ? Should I clean the IAC valve and see ? Or do I need to change it ? How much does it cost approx ?
I owned a Mazda before... never owned a Nissan .. am new to this forum... and I don't know cars very well.. Any help would be appreciated!!
Also, I don't know why autozone said they can't check codes for a *95* sentra, cause the following link says that 95 sentra was OBDII compliant..even though it was made before 96...
Anyway..I had to pay $50 just to get the code.. from a repair shop... don't know how much more I've gotta pay!!!
