With a known good pmd plugged on bumper/heatsink. I have to unplug easy to access sensors along with optical sensor. It will start and be a little smoky. Then I plug all the sensors in and it runs properly. I think the next ride I will bring my Polaris atv and ramps. Hopefully I can move on to new carpet and headliner.So when you unplug either the CPS or OS it will take ALOT of cranking to get it to start. When it does it will be in limp mode but should run nice and smooth. If it fails to start with the OS unplugged it tells you the either the CPS is bad or the wiring associated with it is bad. Same goes for when the CPS is unplugged. You're basically testing the sensor that is still plugged in.
Does it start with the cps unplugged?With OS unplugged it starts, but anything but smooth, I am glad cps works though, as I go through lots of those over the years.
Something is not right if You arr going through a lot of those.With OS unplugged it starts, but anything but smooth, I am glad cps works though, as I go through lots of those over the years.
A lot might be too strong an expression. It’s the only sensor that goes bad on truck. I’ve probably changed it twice since 2012. It’s the one code the ecm throws, that is trusted.Something is not right if You arr going through a lot of those.
I had to replace one in about six years and that one was transferred to the new engine.
I’m confident it will perform just fine in this engine too.
I’ll report back on that.Does it start with the cps unplugged?
