Question about 2002 Lexus RX 300

1 Answer

I have 2002 Lexus RX300 all wheel drive and the engine light went on when I drove over a high snow. I took the car to Lexus service (paid $120 to check it on the computer) and I was told that there was a problem with speed sensor, PO500 code. The engine light went off and I was told that if it goes on again I will have to replace two sensors for $650 and if this doesn’t fix it they will replace transmission. Next day I got the same problem, heavy snow, engine lights on but it fixed itself after a few hours. Is there anything I can check or fix myself before I spend that much money?

If it has only happened the twice when you have went over high snow , it seems to me the sensors have just got wet then sent the signal through to the computer as they normally do , i would'nt worry about it unless it came on constantly ....

SOURCE: Check engine light is on

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.

SOURCE: ? to Replace Timing belt on 2000 Lexus Rx300 with 57,000 miles.

If it is running perfectly I wouldn't think that you would need to replace the timing belt. You shouldn't need to replace that until 100,000-120,000 miles. I would definitely hold off until now unless you have start having some timing problems. Let me know if you have any other questions. Thanks for rating my response and for using FixYa!

SOURCE: High RPMs

yes its related to knock sensor because car is running rich in fuel, and car runs of on safe mode, so overdrive will be off. have you and a friend replace it. remove intake assembly, then intake manifold, but first remove your anifreeze from radiator, trust me you want to remove antifreeze! their are brackets by the fire wall to hold down the manifold, thats the hard part is taking it off and putting that on since not to much space to work on it. on the block you'll see the two knock sensors, has 2 wires each, knock sensors cost between 150- 200 a piece, still cheaper than dealership putting it on. also buy some liquid gasket because you will need that. after putting it all back together reset the ecu and you should be fine,

Be careful to collect all these clips and replace them on the back of the panel. You will need these clips to replace the panel later on.

Normally you need to connect it to a code reader (scanner) and that should give you the information as a code and direct you to the system in the car that may be causing the light to be on.

Lexus 2001 RX300 - What is it when the Trac Off, VSC & Check Engine lights are on at the same time while driving? Thanks!


I have no mechanical experience and my Lexus 2001 Off truck, vsc, and check engine lights came on while driving. After a research on the net. I paid 10.00 for a diagnosis and came up with the code P1135 A/F Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). I went to Autozone store in San Diego and purchase the sensor, 170.00 dollars. Went to a mechanic, lift the car up, pull the sensor out under the car and put the new one. The 3 lights went off. No more faulty codes. Labor 25.00 dollars. Except for the lifting of the car, the change of the sensor is like changing a spark plug. It was no difficult task and it took 15 minutes. 7/31/2010

Lexus rx300 2002 hard shift between 1st and 2nd. Fluid and filter changed 3000mi ago, car has 93000mi


The 1999-2003 Lexus RX300 models have a common failure of the engine computer that causes the harsh shifting of the transmission. You need to get the computer (ECM - Engine Control Module) rebuilt or replaced before it causes permanent damage to the transmission. Even if the transmission is already ruined, the ECM will still need to be repaired. Most often, the transmission is fine though, and rebuilding the ECM will restore the smooth shifts that the Lexus should have. Circuit Board Medics can rebuild the ECM and reprogram it so that you only have to plug it back in when you get it back. See the link below:

VSC means Vehicle Stability Control.
