So let’s start from the beginning. I’ve done a lot of work the last 3 days on the 2001 powerstoke. I started with doing an ebpv delete pedestal, bellowed up pipes, a bd thruster 2 turbo. Then I did the riff raff oil cross over and the fuel cross over. I broke the EOT sensor in the process of all of this by accident. Aside from the sensor being stuck reading at 212 degrees and the SES light on...it ran perfect after it warmed up.
So I replaced the EOT sensor with one I bought from autozone (threw away the box and receipt so no part number) and now it’s reading 284 degrees sitting in the drive way, while my ECT sensor is reading 83ish degrees! I’m in Florida and the truck hasn’t completely cooled yet. It ran fine until it warmed up and was reading over 300,Then it began idling like garbage.
my question is, do you think I have received a faulty or wrong sensor? Or maybe I have a wiring harness issue from crawling around my engine bay for the past 3 days?
As mentioned above, only OEM sensors for these trucks and only the ZF6 manual has the ability to read ECT via a PID. Even then the earlier ZF6 trucks are unable to read ECT accurately, just like the 4R100 automatic trucks.
Most people monitor EOT as a method of seeing internal engine temperature and this is considered a good practice.
Ipzd,
now that it’s been sitting for a few hours.I took this picture with the key on engine off.
this is what I set up on my edge, with no added sensors.
Thank you everyone! I feel very mislead by edge for even having the ect option haha I guess it’s part of the learning experience.
So I unplugged the eot while idling at operating temp in my driveway for a minute and the eot reading went to the default 212 degrees and the truck began to idle much better.
Ordered a motorcraft EOT off of riff raff and just waiting for it to get here. Is there a way to test the connector to make sure there are no shorts somewhere in the wiring? Hopefully the sensor solves it.
John, if it were me I would just inspect the connector harness for signs of damage or wear and wait for the good EOT sensor to arrive. But, if you have some spare time and want to get into the rabbit hole, the image below and the two attachments are some documents that will aid you in digging to the end of the tunnel.
We all would like you to follow-up on this thread if you could once you install the new sensor. I know you said you would follow-up. This Would verify the edge scanner your using would be helpful to others using the same scanner in the future. If that makes sense to you, what I'm saying is it would rule out the sensor ( maybe) and just a fluke reading using edge scanner. But, could also be wiring problems on decades old wiring too. Would like to see what ( Rabbit hole) you fall into and your outcome. Thanks. Bob S.
