I Pulled Code 55 From The Diag. Terminal

[Punkers Slave]

Hi, i have a `check engine' light that comes on after approx. 8 to 10 mins of driving from a cold engine. i have pulled code 55 from the diag. terminal and that indicates a knock sensor.. (bank 1 or 2, lol, i cant remember!) I`m curious if any of the ES300 techs would know whether I have to remove the intake or if the time between engine start-up and the engine light coming on indicates an ECM failure rather than a knock sensor failure. Or any other knock sensor circuit issue that it may point to definitavely. Thanks

Yes, both the upper & lower itnake manifolds have to come off.

It's the sensor, or the wiring. Toyota ECU's never fail. (Unless you own a gen1 Prius)
