Low EOT reading

[alwil]

Datalogged my truck on the highway today, when I started recording my ECT was 184* and my EOT was 137*.
Fifteen min later while still on the highway my ECT was 186* and my EOT was 128*.

I am guessing I need a new oil temp sensor. My question is what kind of symptoms are associated with a bad oil temp sensor?

Bump to the top

Bump again

elevated idle all the time.

[alwil]

I dont have elevated idle, but I thought eot and ect were only supposed to have 15-20* in varience.

[PROMMO]

eot should be higher than ect by no more than 20 degrees.
your oil temp is lower. safe to say bad sensor or blocked oil passage
near sensor.

Alwil as you know I'm having the same issues. Because of the low oil temp reading, I understand that the ECM will sense that the motor is still cold, and will cut fuel and timing, thus why I am having injectors cut out on me in the morning.

It doesn't elevate my idle because at idle in the driveway the temps are normal, as soon as I start driving and putting a load on it, my EOT drops. Even lower than yours.
