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
