My 03 CTS is throwing codes P0700C (Tranny Control Module), P0343C (?) and B2375C (?). Is there a thread on the forum that contains a Code List for our CTS' ?

I searched but didn't locate it.

Any help will be much appreciated.

THANKS GC. Another great source.

I'm getting Code P0343. Do you know how this may affect the vehicle: (Code P0343) - "Camshaft Position Sensor Circuit High Input". ?

It means that the camshaft senor is stuck I the on position. Which there are only two positions, on and off but no where between.

From what understand your engine is able to run by using the crankshaft position senor. But it won't be as effentiant with it.

Might explain why the engine cranks a bit long before it turns on. Guess it's time to replace the camshaft position sensor.

I just replaced the crankshaft position sensor a few months ago after the engine would crank,.. but not start.

THANKS for your reply.

UPDATE:

The Transmission Control Module came in today. It literally only took me about a minute to do the install from start to finish. [45 seconds to figure out how to take the harness off the Module and 15 seconds to install the new TCM].

RESULTS: My 03 CTS shifts like new caddy. Smooth, undetected transition from gear to gear just like I remember.

And the abnormal long crank at start-up is gone as well. The vehicle cranked/started immediately right after the new TCM was installed. I'm wondering if it's just a coincidence or if the TCM interacts with the Camshaft Position Sensor at start-up....?

I should've waited as I ordered a new CPS this morning. Should get it next week. FYI, the Crankhaft Position Sensor was replaced a few month's ago after the car stranded me on the highway.

Anyway, I thought I'd share.. I'm a happy camper.

Greetings, KOT.

I guess I spoke too soon. Still experiencing long crank before start-up.,...and just threw Code P0343 [Camshaft Position Sensor Circuit High Input]. So good call on ordering the part, after all.

The TCM is located towards the front on the right side wheel well. It sits right underneath the fuse box. Take a look, you can't miss it. It's a small aluminum colored panel.

It's retained by plastic hooks and is very easy to take off. It just snaps off/on. The Harness terminal that connects to the TCM has a nifty retention system that incorporates a pull/push slide type lock/release. Took me a while to figure it out.

Affirmative. All codes were cleared after TCM install.

FYI, I reside in Texas. :)
