The software in the PCM uses input from several sensors to determine the timing, duration, and strength of the spark. The camshaft position CMP sensor sends a signal related to the position of the camshaft.

The knock sensor tells the PCM if there is any problem with pre-ignition or detonation. This information allows the PCM to retard timing, if necessary. Based on these sensor signals, as well as engine load and engine coolant temperature information, the PCM controls the switching function of the ICM by sending it a six 5V signals. As long as the ICM receives the signal, it allows battery voltage to the ignition coil.

That voltage allows a magnetic field to build in the coils.Sign In with Edmunds. Howdy, Stranger! It looks like you're new here. If you want to get involved, click one of these buttons!

Meet your fellow owners in our Owners Clubs. January Replaced the IAC Motor today, and no change. We cleaned the carbon away and put the new one in, but it still wouldnt start.

Going to change fuel fitler tommorrow then the O2 sensor. How does that sound? I'm sorry, I thought for sure it was the IAC. But, will you let me know what does work, just in case this comes up with mine again? It's always nice to know where to start looking for the fix. Good luck to you.I just had the egr valve replaced 2 weeks ago due to a check engine light relating to it.

The car has 96k miles but runs good. I'm not sure how long it has been since the fuel filter was replaced since i bought it used 6 months ago. I put a new air filter in it and run fuel injector cleaner throught the gas tank once a month. I'm off work today and would like to do what i can to try to fix this.

I'm not promising anything, but it's the starting point that most people should answer with. Often when the gas mileage drops it is the water temp sensor. Your car will run rich too much gas as long as it the computer thinks that the car is NOT warmed up.

On my Audi it can even be replace with simple hand tools. Of course basic tune up new spark plug, new spark wires, new oil, etc is not a bad ideas either. But don't just go by your "feeling". Don't go chasing bad MPG unless you are sure of it. You could be spending time and money chasing ghosts. So try this experiment first:. The reason you start out with full tank is that is the "repeateable" condition. You want to avoid traffic so you don't use the brakes on the HWY.

Braking will negatively affect the MPG calculation. You use the cruise control so you and eliminate your driving habit as a factor. Without a good MPG calculation you might be wasting your money chasing ghosts. Also you can repeat this test anytime you feel like you car is not running right.

You can also try the same thing but off the cruise control to check how much your driving habit affect the MPG. I have replaced spark plugs, erg sensor, catalytic converter, checked air in tires; I was getting around 16 mpg in city and 22 to 24 mpg on highway. All of a sudden the gas mileage on the highway went down to 13 mpg on highway and now getting 10 or 11 mpg in city. This bad gas mileage started all of a sudden and I cannot ascertain why such gas mileage.

Any help will be appreciated. I have the same problem with my Rodeo. Also use gas treatment to clean out fuel system and bad gas. Check for emission hose leaks too.
