So for the past month and a half after the fail smog check the Tundra has been driven about 1000 miles with the catalyst monitor still incomplete and all other monitors completed. 2000 Toyota Tundra 2596. Hello I have a 2000 SR5 w47.

The downstream sensors only use is to test how well your converter is working. The monitor test runs whenever the right conditions are met regardless of catalyst quality. A worn-out oxygen sensor can cause engine performance problems and shorten the life of the catalytic converter.

Other engine problems such as fuel trim running too rich or too lean oil or coolant burning or engine misfire problems could all lead to catalytic converter contamination or premature failure. Replace the O2 sensor with a sturdier aftermarket unit like those produced by Bosch. In the example of catalytic converters it is possible for them to be marginal and to PASS one test and then FAIL the next.

This can go on and on and onso basically because the system did not fail it twice it. Does that affect the catalyst monitor to be incomplete and recently put a new catalytic converter driver side since the mechanic said a code P0240 popped up. 45 Car O2 Sensor Adapter M18X15 Catalytic Converter Fix Check Engine Light 1Pc Fits.
