Just simply not working. :-) Any help? Where to start?!

 

Checking over fuses in the book and looks like it might be my first fuse? Which controls Security/Cluster2 could be the issue. my security is pretty screwed up, doesn't flash normally when the truck is off, flashes erratically, could be that fuse eh?

 

First thing I'd do is make sure there is coolant in the system. You could do the gauge self check test. Then check the gauge by unplugging the temp sensor and jumpering the connector to max out the gauge, if that works it should be the sensor.

 

ok funny thing, manual says one thing, fuse panel cover says another, please advise!



sorry about it being upside down, i did rotate it the right way butttttttttt, the cmoputer didn't like it apparently.

 

did the gauge check test, it didn't say anything was wrong, about to do another one now, where is this temperature sensor and how do i jump the connector? and yes there is coolant in the system, the gauge never moves lol

 

ok did the test and the temp gauge does move so guessing it is working, where is this damn sensor replacing it tomorrow. thanks zcr

 

ok found the sensor...

 

I'm pretty sure it's next to the thermostat housing behind the alternator. If you take it to somplace like Autozone, they will read your codes for free and you may get a P0117-ENGINE COOLANT TEMPERATURE SENSOR LOW. If not you may have an open circuit somewhere just before the gauge cluster.

 

ok, took a look today, actually went to Advance today, and spent 2 hours there just BSing and looking at different sensors. Seems last night I found and pull the air charge temperature sensor. So today, I returned that and bought the Coolant Temp Sensor. Of course this is after I put the computer on my truck and got High voltage on the Air Charge and Coolant Temp Sensors. Of course I had the air charge sensor unplugged so I knew that was fine, and that was why it threw the code.

Went inside bought the sensor went out to replace it, and noticed it was just simply....unplugged....so, after feeling like a super dummy, I plugged it back in and cleared the codes and voila, fixed...

Could it possibly be that since the gauge wasn't working, the computer was screwing up some how? Cause now my truck does 0 RPM drops when I accelerate. It accelerates perfectly now...

 

Could be, there is a reason for all of those signals. The coolant temp has some input into the fuel mixture (to lean/to rich).
