Throttle Postion Sensor

If cleaning it up and checking for leaks doesn't fix it, I'm replacing the damned thing.

I cleaned the MAF and checked all the hoses, pipes, connections etc... I even removed the black dildo intake silencer thing while I was at it.

I put it back together and it ran great for about 10 minutes, then it started puttering, popping and missing again. I considered putting a bullet in it, but decided to pull the codes again. This is what I got:

1 1 1 - (everything is okay! - NOT)

followed by

1 5 7 - Mass Air Flow signal is/was low or grounded - MAF

1 5 8 - MAF sensor is/was high or short to power - MAF

2 2 4 - Failure in ignition coil primary circuit - Ignition Systems


I guess if I have to put money on something (and I do), it should be the coil. Does anyone know which coil is the primary, the front one or back one?

As to your question about which coil is the primary; both coils have a primary winding and each has a secondary winding. So, the code does not say that one particular coil is the primary. It's saying there is a problem with one of the ignition coil's primary circuits. Code 224 usually points to the ignition control module (ICM) which is used to ground the primary circuit of each coil pack. Here is a link which involves this code and it appears that this fixed his problem. I also had this code in the past and the ICM fixed it. Also, it's quite possible that you still have a problem with that MAF sensor and/or its circuitry.

Oh by the way, the code 111 means that everything is okay pertaining to the diagnostic section of the PCM. It doesn't mean that all of your sensors are functioning correctly.

That doesn't sound promising... I can't afford $200+ right now for an ICM, so it may have to sit in the driveway. Thanks for the link and the advice.

I have a 1992 2.3 no distributer ignition and am on the 3 rd. timing belt at a little more than 200 thousand mile. I ran of the road a while back and got small rocks in my belts and broke the crank sensor after tearing front of motor off and replacing the crank sensor I put it all back to gether but it ran very porly took it back apart and it had also skipped one or two teeth on cam belt put it back in time and its running like a top again.

I finally replaced the last two plugs and wires on the drivers side. Now it's running much better, but still idles sort of rough. I'll re-set the codes and pull them again when I get a little time.

I'm glad it's running a little better for you. Do keep us posted of your results!
