Hi. New to this forum and gotta say I'm impressed with the general knowledge here
Our '95 Camry V6 LE auto. has 215k kms on the clock and it has been well maintained over the years -- such a reliable product that I'm hesitant in replacing the car with anything more current.
Anyway, the ECM recently threw OBDII code P0402 -- excessive EGR flow.
With that code the only other signs of odd behaviour is power surging which makes it feel at times like it's stuck in low gear ..or the power switch on the console is depressed -- no apparent hesitation or rough idling though
Through info on this forum and as it was the easiest spot to start, I began by checking the VSV (vacuum switch valve) under the top engine cover.
The valve is whistle-clean inside. The specs call for a resistance of between 33~39 ohms across the 2 solenoid terminals. Unfortunately, it reads infinite -- circuit's open. I double checked with another known working vacuum switch valve (from under the engine cover) and sure enough it reads within specs (34.5 ohms).
So I guess I should stop testing there for now as this vacuum switch is hooped electrically and will need to be replaced.
I figure going to a wrecker may help with the expense of replacement.
Can anyone tell me which models (and maybe DoM) of Toyotas that have the same vacuum switch? -- they look like they may be a relatively common item for the years involved.
