My 01 Saab 9-5 is smoking from the engine after being driven on the highway for 60 miles. There was smoke coming from behind the engine and it smelled like rubber was being burned. The CEL is on and it is a code 730 which is an incorrect gear ratio. The car drives great when the CEL is cleared but when it is on the car seems to have no power when it is starting out at low speed. When the car gets up to about 30 though it seems to be alright. I was told it could be the speed sensor on the transmission but I want to be sure before I start buying parts that I don't need.

If you need any other info just ask and thanks.

It's the PNP (Park Neutral Position) switch. A common part to fail. It's in the area of your car battery, on the transmission at the end of the gear selector cable. You can find the part on eEuroparts.com. Try "rowing" the gear selector between P and 1 a dozen or so times to try to clean up the oxidation on the contacts within the switch.


The burning rubber smell I can't help you with unless I see pics of what's melting. Try looking down behind your engine to see if you've caught a shopping bag, or if one of your hoses is melting.

For what it's worth, I recently had a similar issue when my power steering pressure line failed, dumping PSF onto the hot exhaust. It would smoke and smell after stopping. That should be quite easy to spot though.

Hmm~ Kinda like when you change the ATF and it gets on your exhaust. Stinky and lots of smoke. Good point to check Dave! :cheesy:

If your smelling burnt rubber or what smells like burnt electronics plus smoking and running rough, the it’s your dic which are common to fail on these.
