SOURCE: code p1130. where is the sensor located

P1130 Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1) 
This sensor is the hardest to get at. It is between the cat and the cylinder block on the bank of cylinders closest to the firewall. Not much wiggle room back there.
Sensor will run you about $225 from Toyota, $275 from Lexus, but you may be able to get a Denso sensor on line.

Good luck and hope this helps. keep me posted.

SOURCE: how to tune up the lexus rx300 can't locate the

This is a lenghty job!! You would have to remove the plastic engine cover to locate the plugs (cover that has the lexus symbol). There are 3 coils(black squarish units) on the front head and another three in the rear head. You must remove these to access the sprakplugs. Front is very easy!! The rear is difficult, you would have to remove the intake(special tools are needed) to access the rear coils and sparkplugs. hopefully this helps

I have 3 codes 1) P0500 2) P0125 3) P1135 1999 Lexus RX300


The PO125 is an indication of an engine running too cold-as if the thermostat were stuck open.For some reason it often sets with the PO1135 even when the engine runs at normal temp.A scan tool will indicate exactly how hot the engine is,don't trust the dash gauge. The PO1135 is a heater circuit fault in the bank1 sensor1 air fuel ratio sensor or oxygen sensor. Bank 1 is the REAR bank on this car...that O2 sensor is not much fun.PO500 is a vehicle speed sensor fault-does the speedo work correctly?it is located in the transmission near the back of the case. once again the scan tool will read vehicle speed and can aid in further diagnosis.

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:
