Codes P0201 & P2146 on '03

[wxman]

I have a 2003 2500 HO. Also have a TST PMCR which was installed in May 2004.



Never really had any problems with codes even after installing PMCR, but recently the truck has been throwing codes P0201 and P2146 (today was the second time in the last month or so). Has anyone seen these codes before? Is it just the PMCR or is this something to be concerned about?

They both sound like injector related codes. The 201 definitely is. I would contact TST about it. They made a change to the injector harness somewhere in the 2004 year. I had to send my older design harness back in and get a new one.

Thank you for your help. Appears it was the injector harness as the truck runs fine with the PMCR removed. Apparently, I have the old injector harness per TST. I'm sending the old one to TST to exchange for a new one.



Thanks again for the help.
