I recently purchased (Sept 18) a 2002 Lexus RX300 2WD 123K, that was only owned by one other person. It does have some minor body dents and dings, the interior is like new. When I purchased it the MILwas on and the DTC code was P0440. I started checking for Vac line leaks as that is what the Lexus dealer had told the previous owners. Then suddenly the VSC and TRAC off lights came on and now the DTC are P1135, P1155, and C1201. I cannot believe that both of the A/F sensors would go bad at the same time.

Since I cannot seem to find the answer for year and model, I am hoping someone out there can help. I have a 2002 RX300 2WD the MIL on, VSC and TRAC off on, DTC P1135, P1155, C1201. I need to find out which of the 3 wires on the pigtails of the sensors I check for resistance, voltage, etc. Also the desired value. I cannot believe that both sensors went bad at the same time. Further history, when I purchased the vehicle in Sept.,18 the MIL was on and DTC was P0440. The Lexus dealer had told the previous original owner that there was a vacuum leak by the fuel tank. Suddenly (after my left headlight bulb blew) the VSC, and TRAC Off lights came on. I cleared the codes with my reader and as soon as the engine is started all come back on.
If anyone has any specs, tips or ideas, PLEASE LMK
