Oxygen sensors are always in the exhaust system. If it has multiple sensors then there will be one in the exhaust manifold BEFORE the cat convertor and one after the convertor. They will be screwed into the exhaust and will have a wiring harness attached to it. For your car probably 4 wires

I have a 2000 Lexus rx300 with a code p1130. what is the location of the sensor causing this code ?


That code doesn't mean any sensor is defective, it can be the sensor, problems with the engine or a faulty fuel injector or the wiring or the engine control computer that triggered the fault.

The engine light and VSC light are on (Vehicle Singapore 2004 Lexus RX 300. Diagnostics report Error code P0037


your o2 sensor is bad. vsc will go on for any small DTC displayed on the MIL (cel)

P0037 LEXUS P0037 LEXUS - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 2 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
Possible causes - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) When is the code detected? The P0037 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit P0037 LEXUS Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECMcontrols the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

Lexus rx300 engine light is on P0171 how to solve the problem


P0171 is saying that bank# 1 sensor one is in a lean condition thats an oxygen sensor This is an incorrect reading because the 02 sensor is malfunctioning for some reason or your haveing some kind of fuel delivery issue its more likely that it is the sensor it would be the closest to the front end of the vehicle and would be located in the Y pipe comeing off the cylinder head exhust ports but # 1 is the closest to the front

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.
