Question about 2001 Lexus RX 300

2 Answers

Check engine light is on

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 !

    My error on the catalytic concerter phrase. To date, the dealer has replaced the Bank 1 and Bank 2 Air Fuel ratio sensors and the Mass air flow sensor.

  • Joseph DaMico Apr 23, 2009

    Dealer now says that there is a broken stud at the manifold which is causing an exhaust leak that is affecting the oxygen sensor. Says that I need to fix the stud before they can get an accurate reading. Estimate = 6hrs of labor totalling @ $750

    They have to pull down the exhaust to get to the stud.

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.

    Not sure how they can justify six hours labour

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.

My wife got a VSC code on the dashboard and a Check Engine light as well on her 2001 Lexus LX 300. When the mechanic diagnosed the problem, it does not specify which O2 sensor it is. He said he also...


VSC is a Vehicle Stabilization Control. The oxygen sensors have nothing to do with this. Just a heads up, I work for BOSCH and I make these oxygen sensors everyday. The VSC is exactly what it states. One of the Oxygen sensors could be bad, but from someone that makes these. The aftermarket is the same thing as the OEM. Some will say "that's not true" but the only difference is the marking on the part. I would have the mechanic pull everyone out and check for break down. It would really be a good idea if you change all of them. Good Luck.

VSC/ Check Engine Light


My 2000 Lexus GS 400 just had the VSC/VSC off light and the check engine light come on. I would have to push the accelarator peddle all the way down to get it to go. Took it to the Toyota dealer and the code pulled up as the Throttle Position Sensor was out. Purchased one and having it put in. Will update if this fixes the problem.
