My celica has failed mot on emmisions around 5% iam also getting poor mpg have changed front 02 sensor cleaned vgr valve and changed spark plugs any ideas
Air fuel mixture may be it. Also it could be a bad catalytic converter. Also the timing may be the culprit.

Hi,
can't tell you exactly where it is, but it will be on the first section of the exhaust (usually within a fooy or so of the manifold). There are a few types of Lambda sensor but they basically do the same thing. If you are a bit of a handy man, consider buying a universal sensor off ebay, they are much cheaper and just as good. You will have to use your original connector, so you'll need a pair of snips and some electrical connectors (scotch blocks etc)
In your ebay search type "universal lambda sensor"
hope this helps.......Dave

Put key in ignition. Hold down one of the key buttons and hold it down while you turn the ignition on. Door locks should pop up and down. Then release button and remove key.
Testimonial: "Thanks for the feedback. . is this programing done using the new key first or do i need to use my old key to start the Programming process thanks"
