Sorry for the long delay.
Delivering fuel and supplies to a friend in the mountains that's without a car or phone.
Still getting 12v on fuel pump relay(pink wire) when ECM if supposed to send to ground.
I understand if the CAS sensor at the crank was bad, I should at the very least get a code for misfire?
engine runs great otherwise.
I bought and used a elm-327 to scan for codes.
The only stored codes were for the MAP sensor.
Unfortunately I did not check freeze frame data. (Frustrated at myself)
Cleared codes. Drove 15mi on freeway.
13.5 miles off road, very rough secluded snow(delivered fuel and food to a friend in a cabin with no car)
15 mi freeway cruise home(total 65mi round trip)
On the way home after about 7 miles on the freeway at steady cruise(60mph) very flat slight downhill,
CEL light triggered a code P1408.
Engine ran excellent for the trip.
Warms up properly, RPM drops to steady 800
Enters closed loop,
O2 sensor voltage swings properly.
I AT and ECT temp sensors read as they should.
MAP looks proper (need to have wife drive while I watch MAF load)
Voltage good.
TPS looks good throughout range
Cleared codes no codes returned.
Runs good, tach works idles well true mileage good.
I took screenshots of the ELM software (torque pro sensor data)
However my phone met a untimely demise(mountains, snow, fire). I'll try to recover the screenshots and post them here.
Thanks for your time and experience.
I use the tracker to travel to stone very remote places. Your site and documents I've downloaded have saved me very long hikes more than once.
