I have a 1999 Mazda 626 ES V6, auto trans, FWD, and 91K miles on it. I have the Check Engine light on since a few weeks.
I have the following error codes using OBDII tool
P0133 - Heated oxygen sensor H02S RF circuit malfunction
P1131 - Heated Oxygen sensor Bank1, sensor1 (H02S11)
P0040 - EGR system leak detected
The car starts, and runs fine, no strange noises, or stuttering. Recently, I had the fuel pump replaced. Gas lid is closed tightly.
I would appreciate if someone could help me get a rough estimate for repairs. I'm trying to make a decision whether to get the repairs done or get a replacement car. Thanks very much!
