@ Mlefu. Is it a mercedes axor 2540 or is it a GT2540R ama ni gari gani?

I am looking for an Oxygen sensor for a RAV4 2002. Tried Toyota And Alfa Motors but they don't have it. Does anyone know where I can get it?

Any more info on the wingroad. i would really like to damp my toyota and acquire one.

Freelanders have a major water pump problem. I know of someone who has changed the engine block twice before they realized what was happening.

He he he Toyolander nice one kenyans are crafty i like some of our mechanics although am yet to see someone who can build a car.

I agree wingroad like most of the nissans have very good engines. the one area its weak on is the suspension system with our roads it gets knocked off abit faster.

UNDERSTANDING YOUR SENSORS
When a sensor voltage falls out of specifications, the computer will illuminate a "CHECK ENGINE, SERVICE ENGINE SOON, OR MAINTAINANCE REQUIRED" light on the dash i.e the Malfunction Indicator Light(MIL). If this light is on in you car, it means the computer has received a bad reading from one of the sensors.

OXYGEN SENSOR: This measures the exhaust oxygen content. The computer fine tunes the mixture using data from this sensor.
FAILURE SYMPTOMS: Poor fuel economy, driveability, light on dash.

THE HEGO SENSOR (Heated Oxygen Sensor): This is just an Oxygen sensor, except it's HEATED! Heated Exhaust Gas Oxygen sensor. It is electrically heated so it works immediately on engine startup: the other type must be heated by the exhaust before it starts to work. Computers using these place a lot more emphasis on the data from the Oxygen sensor, and use this data sooner while the engine is still cold.

It is recomended to change this sensor on clocking 50,000 miles whether the MIL is on or not.

@XSK also check with Commercial Motor Spares... If they don't have them, they might be able to ship them in for you. They do spares for major Japanese brands

@XLS yes the sensors are available at Legacy auto spares at 13,000 for new ones and they also have second hand. We will charge you 2,500 for fitting and the error code delition!
