Hi,

I have a 1999 Honda Accord LX and this the second time the check engine light has been on in 2 months. The first time it was the o2 sensor but I do not know the cause of this one. My car has 197,000 miles on it. I have noticed that my A/C seems to be going from cool to warm with all the proper A/C lights working. Could someone please give me some advice on what to do? Thank you!!

 

I have no clue what caused the check engine light to come on. Get the code scanned for free at places like Autozone and post the code on here. The codes are P####.

The a/c should not cause the check engine light to come on. Start the car and turn on a/c. Are both radiator fans running? Check that the clutch is constantly engaged with the a/c compressor pulley.

To determine if the system is adequately charged, you will need a manifold to accurately determine the high and low side pressures.

 

also let us know if car is a 4 or 6 cylinder AT or manual tranny,,,,,,,,
