ECM-60 Reset valve camshaft- faulty signal
ECM-91 Torque reduction- faulty signal
ECM-A1 Engine coolant temperature sensor- faulty signal

WTF! And no CEL still.

They sort of fixed the idle adjusting the throttle cable. It idles in the normal range now, but when I put it in park, the idle jumps to 1300 RPM's?

 

Something is wacky here.

You can change the ECT and thermostat yourself.
But the ECM-60 cam make it run really wacky as well.

 

It runs perfect!
I don't understand this. There is no CEL on at all. If the CEL isn't on because of this then I'm not gonna spend that kind of money to fix something I can't feel. Do you think that's wise?


The throttle cable adjustment worked. It must have stretched out since they put the new one in 10 months ago. It idles normal at 750 RPM and when I put it in park it goes up to 900. Perfect!

 

I'm thinking these codes may not be active? If they were active wouldn't I have a CEL?

The thermostat works normally, car doesn't overheat or run cold.
I don't even know what a camshaft position sensor is!

 

The cam shaft sensor tells the computer the position of the cam so the computer can fire the injectors and coils to work so the car can run.

The light will not always be on for active codes. But they might have been Non active.

If they were cleared see if they come back.

 

They were cleared 3 days ago.
Is this something I should get taken care of even though I have noticed no change at all?

 

If they come back I would. But if they do not come right back worry about it when they come back.

 

mmmmmk.
How will I know if they come back? They were present on the computer but no CEL was lit last time.

 

When they first some on it should throw the light.

 

What bothers me is that it did not last time.

I'm thinking about giving it to them and having them do the timing belt and everything just to not worry about it. How much would that run me?

 

Quite a bit get a quote from them because prices vary.

 

Someone just told me on another forum that you are supposed to change the timing belt every 4 years regardless of mileage?
True?

 

Check it 7 years 70,000 miles.

 

What just look at it? LOL!

The dealer did a full check out on my car when I first bought it at 88,000 miles. Do you suppose they looked at it then? Like I said I don't have any squeaking on cold mornings at all, hardly any running noise or anything.

PS: CEL still not on 4 days after clearing the codes. Maybe they were bogus after all.

 

jrgillespie630 on s40concepts.net said you walked him through replacing the sensor and thermostat. Looks like there is no software that is needed?

Do you know where that thread is?

OK I found the threads.
I ordered thermostat, coolant temp sensor, and crankshaft position sensor for $115!!
How do I replace the crankshaft sensor?
And is the coolant sensor going to be generally the same replacement procedure as his 2004?

 

Yes you just look at the timing belt if it is cracked it needs to be replaced.

The crank sensor is a little bit of a pain the wiring is the worse.

That should be the same as the 04 as long as it is the early 04 model.

 

I'm thinking I'll call an independent European auto place in town and give them the sensors and tell them to fix it. And get a quote for the timing belt as well.
Still no CEL, BTW.

I'll still save money buying the parts myself I think.

 

The timing belt lifespan on these s40's is supposed to be 90k-110,000 miles before timing belt replacement. It's a waste of your money and time and perfectly fine belts to have them replaced every 4 years regardless. But that's just my two cents...the choice is yours.

 

My 2 cents is 7 years 70K

 

So you think I should suck it up and get it done?
