ECU code 17

[fast8seccamaro]

I got my jaws pipe back from getting ceramic coated and installed it on the sled with the temp sensor. When I started the sled I got a ECM code 17. I visually inspected both connectors and used a ohm meter on the sensor and seen about 200ohm and when I used a small torch to heat the sensor it climbed over 300ohm before I stopped, I would think the sensor is alright! Where should I be checking next? The wires at the ECM to make sure the wires going thru the sled and the connector is actually good? Anyone have a pin diagram for the ECM connectors?

Not sure why it would do it, but I just got mine back as well, I will fire it up tonight and see what it does.

hmm...I thought the resistor bypass that some people do and or purchase is at 450ish ohms..??...or am I wrong

This is a comparison of the arctic cat sensor and the Chev duramax sensor that everyone's using. I don't have heat in my garage and it was around 0degree Celsius (32f) in there and was reading around 200ohm which is about right and got hotter with the torch! I'm going to borrow a buddies spare harness with a resistor to try tonight!(

If it is topping out at 300Ohms, I think your sensor is bad. Everything may look great on the sensor, but the tiny wires between the sensor and the plug are small and brittle. The best way to keep them together is to loop the wire back on itself and zip tie it to help dampen the vibration. Most of them came stock this way.

It only stopped climbing because I called it good all pulled the heat away but I still think your right and the sensor is bad! I'm headed home with a known "good connector and resistor" and will try it out! Thanks for the help!

What year Duramax part and are the connectors the same.

Sorry, it's at home on my computer! Just google "arctic cat m8 pipe temperature sensor" at it should pop up! The sensor is the same but the connector is different, I was just going to solder and heat shrink it.

Did you run it before you put the jaws pipe on?

do you also get error code ECU 1?

the dealer replaced the cable harness seems to be working now but i haven't tried it in the snow yet.

OK, I found the problem and it wasn't the sensor. I borrowed a known "good connector and resistor". Plugged it in and fired the sled but still had the ecu code 17. I basically pulled the whole wiring harness out of the sled and found the ground wire was rubbed thru where the wiring harness runs under the jackshaft and tunnel. There was also a bunch of damage to the plastic loom beside the exaust can where the wiring harness passed by the motor mount. Both were fixed and I used 1" rubber heater hose for a softner. Fired the sled and all is good except im still not impressed that a sled with 500+/- miles would have wiring harness damage already! I would of tried to get warranty but with a 925BB, headlight delete, aftermarket exaust ect I know itll wouldn't of went good and not worth my time. And I know the wiring never got moved when installing those parts, so I know it wasn't my fault! lol

Good work tracking it down.

We had this same damage happen on one of our sleds. I posted pics earlier this year. Dealer warrantied it and replaced entire harness as they said cat wouldn't just let them fix the rubbed spot. $550 for a little rubbed wire. http://www.snowest.com/forum/showthread.php?t=335736
