I think my Temp gauge in my truck is inaccurate. It has a sensor for the ecm and for the gauge. I replace both yesterday along with the thermostat and am getting a reading of 120 on the dash gauge. Would a mechanical gauge suffice in this situation? Also as long as the ecm sending is new it shouldn't be throwing fuel at it say its "cold" even if the guage isn't workin?

the gauge is probably just fubar. on my old fiero i could tell it went into closed loop by unplugging the EGR. i would try and cycle it once it was up to temp and throw a code if it was unplugged. that might be a way to check and see if its getting up to temp and doing switching over.

what yr truck?
if OBDII should be able to have it scanned and see what the ECT is reading/telling the ECM.
But you are right, a mechanical gauge can be used to tell you what the temp is, as long as the ECM is getting its number.

It did but I put new plugs and wires and that seem to clear it up.yes the mpgs suck. Im hoping changing the ecm sensor helped that though. Im not getting any cel lights.

Also when I got to work this am, I went out and shot the radiator hose with a infrared temp gauge and it was reading 180. This is what really led me to believe the gauge is fuxed.
