2.0 16v lambda probe

Hi, just after some clarification. Where is the lambda probe on a 2.0 16v?

How many wires does it have and exactly what does it connect to?

Pics would help if anybody has them.

Just in front of the cat, pretty sure its a 4 wire heated sensor. Connects to the snakes nest I have behind my engine bay :D

Yeah, the sensor wire goes up behind the head against the bulkhead and connects to the main loom at a bracket.

Thanks, I'll take a proper look and add it to my list of things to change.

I replaced the Lambda sensor on my car 94 2l 16v 9A engine last year. The correct Bosch part is 0 258 003 165. Its sold by http://www.carparts4less.co.uk as their part no 710441475 @ £57.54 inc vat and delivery. (if you quote CP5LESS then you get 5% discount off that price). I doubt youll find it cheaper anywhere else-the consensus is that its best not to buy some other cheaper unit-the Bosch part is the one to have.

 

I should add it was impossible to remove the old sensor in situ. I tried releasing the cat at the front end for better access to no avail. I ended up removing the cat from the car and used heat to try to free the sensor. A long ratchet was used to finally free it. Refitting was straightforward with new bolts/nuts at the fore end and a clamp at the rear.

 

The fuel consumption increased from mid 20s to lower 30s on renewing my lambda sensor.

They're not always that bad, the one on my 8v (similar fitment to 16v) came off fairly easily although there's not much room to swing a spanner :). NTK ones are pretty good too.
