CPS

What is a CPS on 7.3 truck, these go bad often, correct?

[Diescipel]

Yep, do a search and you'll get a bunch of info. Basically, yes, they go bad, symptoms are the engine will crank, not start, AND most importantly no RPMs will register on the tach. Part is cheap (I got mine for $25 on eBay as a back up) and relatively easy to replace (front top of engine). BUT there was a recall if I recall and they should have been replaced with new and improved versions.

EDIT sorry forgot to say CPS=Cam position sensor.

What's your truck doing?

[KYStroker]

nothing yet! I just wanted to know what it was, I get an extra to keep in my truck! Thanks a bunch

[BuickLeSabre1960]

yep Cam Position Sensor. I had to replace mine this morning, luckily had one in my dash

Are there any other little things that these 7.3's are bad for? I had 2 Dodges in the past, they where notorious for burning up injection pumps and transfer pumps.

Others will know better/comprehensively. I'm a noob. But the other recall they had was for wiring fires with the cruise control, so make sure your truck has had that taken care of.

There's all kinds of little things, nothing major. Well, except that the 99-03 auto trannies aren't quite up for the torque of the 7.3, but neither one of us has to worry about that :-). Other things that I've run across in reading up before getting mine (this Saturday! woot) include under valve cover wiring harness, and... shoot that's all I can think of. It's all here on the org so just read away.

Thanks! I am just looking to keep a dependable truck, may put a mild chip in later. Don't want to juice it up, need to use it!!!!
