EOT high?

[bluedge8]

so I have left my scangauge on eot for a while now and the last couple of times I've driven it, It has reached 270 degrees'. So do you think this could be accurate? or is the sensor bad? if it is getting that hot, would it be safe to assume the oil cooler is plugged? if so can it be cleaned, I've never had one apart. btw the coolant temp is fine. as well as trans temp.

I think my first point of diagnosis would be to get an idea if that sensor is reading right. Maybe with an IR temp gun and also see what temp the oil reads at with the truck at a known temp like parked in a garage over night.

I checked my AE this way. Right when you shut the truck off leave the key in on position. Then quickly pull the plug out of top of HPOP and stick a thermometer in there. Compare results.

I didn't have very good luck with an IR gun.

How much offset was there?

My money is on a sensor issue.

How much offset was there?

Only a few degrees. Sensors are like +-5-10 deg.

thanks guys, I won't be driving it for a couple of days, I'll let you know

I did manage to check my eot before I started the truck, 97* with an ambient of about 25*, so I will get one ordered.
