Passing Inspections with Certain Error Codes

[paulrosenthal]

Hey PT Cruiser people,

I've had a few questions before, and you guys have been GREAT to answer them, and I appreciate it a lot. I am back with another question. Let me go ahead and explain the situation.

In Missouri, certain cars (includes the PT) must pass two inspections. It's about to be my time to have the car inspected again. Since last year, I have added the "burp-free shift mod" which involves cutting a wire from the harness. I have noticed since doing that mod, a scanner indicates two pending error codes, P1793 Pending (TRD link communication error) and P0700 Pending (Transmission Control System MIL Request). I taped the ends of the wires, so I can re-assemble the wire if need be to pass the tests.

My question is: Will my car pass both inspections with these codes? I know that if the PCM throws certain codes, it will not pass inspection. I thought those were exhaust, cat converter, and emissions codes. I don't know about Tranny codes, though.

If anyone has an answer to this that would be great!!!!

Thanks.

Paul

Never heard of the shift mod causing an error code. I think you have another problem.
I'm not familiar with your state codes, but chances are the internets has the answer...

Thanks Quicksilverdon! My mechanic said that the error codes were pulling up for him, but he wasn't sure why. I don't know what that TRD Link is...any ideas?

Thanks!

I found this using Google:

"The P1793 is unrelated to the shift concerns you are experiencing.
Several hunder burp-free shift mods have been done without a hiccup.

However, to satisfy your tech and the diagnostic flowcharts, I suggest you re-connect the yellow wire to prove that it make no difference.
Have the codes cleared when you connect the yellow wire and start the testing from a stock baseline.

The P1793 will only show up with a professional scanner set to read the transmission control module data.
P0700 is a generic engine code telling the tech to look in the TCM for tranny codes.
Since neither code presents an emission failure, the check engine lamp will not light."

That's from MX-5, who originated the shift mod.

Thanks again!

Do you know how I can look at the TCM for Tranny codes?

It requires a code reading device - try autoZone, etc. They plug in and read codes for free.

[paulrosenthal]

I have one at my house, that's how I got the P1793 and P0700. Will the AutoZone/Advanced Auto one show me more codes?

Dunno - look at what MX-5 wrote that I quoted above:
"The P1793 will only show up with a professional scanner set to read the transmission control module data.
