what is this sensor?!??!

[danpayton]

Just bought a 1999 e450 cutaway van 7.3 powerstroke

1) there's a sensor with the electrical connection tabs broken off... is this the oil temp sensor? or what sensor is it?? (see pic)

2) it always starts up fine... but it seems like I have to crank on it for 1.5 - 2 seconds longer than ANY other powerstroke ive ever started.

when it starts, idles perfect, and no smoke.. nice and smooth.. just slight extended crank time.

just replaced fuel filters as well.

thoughts? are these things related??

thanks!~

Look just behind that sensor, on the back of the resivor on the driverside. That is where the EOT sensor usually is. If its not then I would assume they had to move it up there on the vans for some reason.

Not sure the difference between the SD/F-Series and the E-Series, but here is a sensor diagram from a SD...

yea if the sensor is in that hole on top, i wonder how youre supposed to check the oil level.... wonder if someone just switched the sensor for the plug, and didnt realize it... it was a fleet vehicle for 370k miles...

so if the oil level is low in the hpop tank, will that causes an extended crank to start? and what would cause the oil lever to be low in there?

It seems like that sensor should be UNDER oil, to accurately work.. or at least have wires connected to it!! lol

I've got the same problem with a 2003 E350. Have to crank it longer than it should to start up. But mine runs ruff and lack power. Trying to track it down. I will post back when I find the culprit. I ordered a new cps last night. I heard that can cause some running issues. Also getting a scanner tomorrow. How you can figure it out.
