I have two problems on the 99 TL. My check engine light came on and the error said it was my O2 sensor bank 1. I change it and two weeks later the check engine light came on with the same error. The guy at AutoZone told me it could be my fuel system not mixing the gas properly. Any suggestion?


Second on my way home about 30 min ago, after a 2 hour drive, my AC temperature went up then some white stuff started coming from the vent. I turn off the ac and pulled over check to see if there was a visible leak. Did not see any turned back on the AC. It cooled for a few min then stop cooling the white stuff started coming out. I turned off the AC and drove home. I had my ac pump and condenser changed about a year ago, and I am sure my year warranty expired about 3 weeks ago. Any suggestion.

 

There's a lot of symptoms giving valuable information for diagnosis. I'm sure you'll get some solid help with the unique problems (never heard about A/C making it rain on the driver).

 

you replaced the front O2 sensor--with what brand? plug and play or tap into wires?
did you reset the ECU after that, so it learns working new part info?

 

I used a Bosch o2 sensor plug and play. I reset ECU by disconnecting the battery for a few min to remove the error code.

 

Get DESNSO, NGK or OEM Honda some bosch arent compatible and make sure u replaced the right BANK and reset ECU with ODB2 scanner.

 

I took my car to the shop, it turned out the expansion valve was stopped up, so i had it replaced.
he also told me my fuel pump might not be operating at the correct pressure, but it could also be the O2 sensor. he recommended a DESNSO
