So here is some data:
- tested sensor in engine at pins and reading is 58k ohms (garage at 50 degrees)
- chart says should be around 56.7k ohms so thinking sensor is ok
- volts to connected with IGN On is 4.65v (I know not 5 but...)
So sensor is or should be showing EEC a “cold” engine.
So is the verdict a shot EEC?
Anything else I can check?
Note/background:
1.) no CCR as this is a project car and have the EEC wire (ground) for Fan Control to a stand alone relay.
I had spent 2-3 days testing circuits, starter system, etc and everything seemed fine - fan did not come on, fuel pump came on for 3-5 sec and then shut off, ABS relays cycled as they should.
2.) Is there a specific parameter in the tune I can check? I have a Tweecer that I just started playing with.
This was after about issue started, I did hook the Tweecer up and used a different known tune and same thing happened - Fan always on.
But there was also a “junk” tune on there as well and:
- fan did not come on
- fuel pump ran continuously
- tested sensor in engine at pins and reading is 58k ohms (garage at 50 degrees)
