O2 sensor UK part no. and excellent test info guide website.

[Andrew_Ennis]

Does any one know of a replacement part for the O2 sensor. The part nos. on the Repairs guide are not available in the UK or the part numbers for the UK are different. I went through the parts book at the Lucas UK part supplier with no luck.

Also i have found an excellent write up on O2 sensors and how to test them. Wonder if Alan could code in a diagnostic program in to Elanscan so you could test if the sensor is working correctly.

I got one here (look at parts for the '91 Isuzu Impulse RS). I got the KEM (its identical to the original) it cost $69 + $28.75 postage and came in a couple of days. I can't remember if I got hit for duty as well.

The Bosch universal 3 wire sensor is ok as well you'll just have to re-use the old plug.
