Mitsubishi Grandis Elegance 2.4L Lamba Sensor
Hi All, I am the owner of a Mitsubishi Grandis Elegance 2.4L Automatic Transmission in London.
The warning light on my dash is due to the oxygen sensor.
I've been told by Mitsubishi that my car has 4 oxygen/lambda sensors - 2 on the manifold and 2 on the down pipe before the catalytic converter.
I had a diagnostic done at Halfords and they informed me that it was a bank 1 lambda sensor fault and advised me that I should change both.
(My advice is make sure you are given the promise that any diagnostic will pinpoint which sensor is at fault to avoid you spending £50 and being none the wiser)
I have spent a long time researching the lambda sensors but if anyone can advise if I need to change both pre cat sensors at the same time I would be grateful and also which sensors I need to buy.
The mileage on the car is 85000 miles and I believe the sensors haven't been changed before.
Also, will the lift go out once the correct sensor have been changed?
