Bank 2 reffers to exhaust manifold where the # 2 cylinder lies. Depending on how many sensors you have on that side you will find the sensors there. The sensor clossets to the engine would be sensor 1 bank 2 and if you have another on bank 2 it be reffered as sensor 2 bank 2. The same applies for bank 1 sensors the one cossets to the engine is rtefferred to sensor 1 bank 1 and sensor 2 bank 1. Hope this helps.

I recently changed both knock sensors and wiring harness on my 99 Lexus rx 300! I purchased the parts on ebay and they state (OEM PARTS) Check engine, P0330,


code p 0330 refers to knock sensor (KS)2 bank 2 ---circuit malfunction===causes wiring--KS---ECM
it is possible that in changing the harness there is a problem connection or the connection to ks2 is not correct ( not on properly)

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.

My car came up with a P1150 code for my lexus rx 300. what does that mean?


Tests/Procedures: 1. With the sensor disconnected and the key on, check the voltage at the wire harness side of the connector. The Black wire should have 12 volts the Orange wire and the White wire should be approximately 3 volts.

2. Reconnect the sensor connector and check the voltage on the Black wire on start up. It should remain battery voltage. The Orange wire and the White wire should vary slightly in voltage from 3-3.3 volts but the sensors will not change much.

3. Install a new sensor. Potential Causes: Defective Air Fuel (A/F) Ratio Sensor
Tech Tips: This is a common issue with the air fuel ratio sensors. The firewall side will fail and the technician will install a new sensor and then a few days later a code for the other sensor will appear. Always replace these sensors as a pair.
