Pinion Factor 2006 PT Cruiser 2.4L Turbo

Having been down this road a couple of times over the years specifically on the PT cruisers in this time frame, the vehicle speed calculation and journey of the data varies between manual transmission and automatic transmission as well as with or without ABS. Sometimes the diagrams are not comprehensive so keep an open mind. The first flag to address would be whether or not the computer that…

Thanks for your quick reply Kerry. The PCM is a reman with software blanked to the factory default. We flashed it to the appropriate software (calibration) using J2534. On 2005 Pt Cruisers we can easily set the Pinion Factor under the TCM menu in DRBIII Emulator but we can't find any option to do the same thing for 2006 PT Cruisers using both DRBIII Emulator and Wi-Tech. And do you have the…

Pinion factor is in the TIPM not the PCM, the 05 PT did not have a TIPM and was a DRB only vehicle the 06 is a hybrid with a TIPM which is why some functions need wiTECH others need a DRB

Pinion factor is in the TIPM if memory serves me correctly, been awhile since I've had to work on one personally. But didn't mind them as most others at the dealership's I've worked at would avoid them.

For some reason I think I remember having this issue and I had to restore vehicle configuration with witech. Just know that currently snap on Altus, Mitchell, auto auth, and tech authority are in a blackout.

Hi Robert, Thanks for the heads up. Yes, they are down since last night. Do you know or remember by chance which option on WiTech allows me to reconfigure the Pinion Factor for these 2006 PT Cruisers?

I had one of these once and the speedo wouldn't work after a pcm was replaced. It has no way to do the pinion factor. I'm certain I had to do a restore vehicle configuration to get the speedo to work.

How do you do the restore vehicle configuration?

Under guided diagnostics restore vehicle build configuration

Thank you, Robert.

You are welcome. Just trying to assist a fellow tech when I can. Sadly all FCA systems are down so probably not going to be able to do it today.

Yep, unfortunately nothing works now!

Use a snap on scanner has worked for me in past

Change the tire size to something different than what is on the vehicle, then change it back to the correct tire size. That should fix your problem. It’s common with PT Cruisers.
