Hello, my trouble is my engine is running rough. Even after all the recent repairs. Newest repair replaced the PCM/ECM. Engine performance did improve somewhat but now I've got a new list of codes/issues to deal with.
My question is this? Where to start first. I'd like to start with this code first. One at a time to keep from getting confused. 1.P2004 runner control open bank#1.
2.P2017 intake runner position/switch high bank#1.
Please help me with these two codes.
First. Added information from my previous repairs last week. Removed intake manifold disassembled butterflies and cleaned the flaps of carbon wd40 replaced intake. Replaced the throttle body same time.
Thanks. JC

Hi,

If I had the vehicle, I would likely start with the P2017. I read through both of the diagnostics and an open circuit appears to be the most likely (but not the only) cause. An open circuit simply means a wire is disconnected, broken, grounded and anything that would cause high resistance. On the flip side, it could also be a short to power. Basically, it receives 12v rather than the 5v reference.

With that, I attached the diagnostics below related to the P2017. This will require checking wiring and connectors.

Here is a link you may find helpful when testing/checking wiring and connectors:

Take a look through the diagnostics and let me know if you are comfortable performing the test.

Take care and let me know what you find.

Joe

Hi Joe, I will try anything. I need to know what I'm supposed to use to test the wires with? Test light, ohm meter etc. I have a multimeter but don't know how to use it. But if you coach me I'll be happy to try. Thanks, JC

Joe, here's the meter I have can you look and tell me what settings to set it at for the voltage test? Sorry but I've never figured out how to use it.

Hi,

JC, that is perfect. You can use that for nearly anything electrical on the vehicle. Do me a favor. Read through this link. It explains how to use one. Note that it indicates a voltmeter. Your multimeter can do anything the voltmeter can do plus more. You will notice symbols in the link and on the meter being used that are the same as what's on your meter.

Let me know if this helps or if you have other questions.

Take care and I'll watch for what you find.

Joe

Okay Joe, let me verify my first step. I set the meter on volts. It's reading 0.0.0v
I'm going to test the runner control valve harness connector number 4 pin key on PCM unplugged per instr. So it says if there's 5 volts there's an issue?
Is this right? I should not get 5 volts unless there's a problem with that wire?

Hi,

With the PCM disconnected, there should be no voltage. If there is, that means there is a short to power at some point.

With the PCM connected, yes, you should see a 5v reference.

Let me know what I can do to help.

Morning Joe. I tested for the the 5 volt test and the reading I got was 0.0.7/0.0.8.

It sounds like you may have found the problem. The only other thing I would suggest is to check the related wire for continuity to make sure there isn't excessive resistance. Or, you could back probe the wire right at the PCM to check for the 5v reference. By doing that, you bypass the wire.

I hope that makes sense. Let me know if you have questions or if there is something I can do to help.

Take care,

Joe
