16 = Idle speed indicator defective. Q. How do you fix this or check this? This is a M104 engine. Am I giving enough information? There's got to be someone out there that had a code 16 on a M104. Where do I start? School me!

Strictly a guess on this one being that yours is a CIS-E driven M104, but I'd look at either the rotational sensor inside the AC compressor or the CPS.

CPS = crankshaft position sensor.

Too bad you don't have a EEC-IV driven Ford as code 11 on those means all systems are GO.

49$ for front and 139$(German Star) for rear CPS I didn't know there was two?:confused: Where should I start?

The front one is for diagnosic only, and since the car is not stalling without warning I would do that one first. Besides, it's the less expensive one.

Have you tried disconnecting the battery to clear all the codes. If you have the stock radio, make sure you have the code before disconnecting.

No, but mine is a CA car and has the code reader box (push button option) and I can clear the codes by holding the button for 10 sec. Will disconnecting the battery clear it even more?

Not cetain if it will clear the codes further Sam. I'm sure another CA owner will chime in on that one. If the car is running fine, leave well enough alone. You can test the the OHM rating on the crank position sensor with a meter. IIRRC it should be in the 970-980 range.

The upper photo is the cam position sensor. Super easy to change and not much money. The second image is the idle control valve. Not a part that fails very often. Easy to remove and clean with carb cleaner to make sure it rotates freely. It is no more that a rotational electro magnet. The single (voltage) comes from the ECU and allows the opening inside the ICU to vary, depending on idle speed need.
