Question about 2001 Lexus RX 300
I have a 2001 Lexus RX300 with @ 75K miles on it. The check engine light went on followed by the VSC. Brought it to the dealer where the computer reads: Code P0171, P1130 A/F sensor B1S1 and MAF sensor 2.00 replace both sensors and clear codes. Authorized work and vehicle returned. On the ride home, light goes on again. Returned vehicle next day to dealer where they inform me of the following computer read: P0125, P0174, P1150, P1153 A/F sensor B2S1 1.50 replace sensor and reset ECU. I pick up the car after the repairs. Two days later after driving the vehicle, light is back on again. Do they know what they are doing ? What do you think is wrong. Now they are alluded to catalytic computer. Please help !
No such thing as a catalytic computer... there is a catalytic converter ... part of the exhaust system so they may now be "guessing" that it's an O2 sensor. take the car to autozone... they will scan the codes for free.... post the codes here tho the lads and lasses there are pretty clever and will probably tell you what the codes mean.

I had the same situation a couple of times. It happens a couple of days after air filter is changed. The first time, I took it back to dealer, they did the reset, and VSC and Check light went off. The second time, I just leave it there. After two weeks, lights went off. This week, I have this situation for the 3rd time. Still wait for them to go off automatically.
