Well, I have two of them.
First, I have recieved the P0336 (Crankshaft Position Sensor Performance) twice now, and when I use the high idle on the truck it seems to surge about every 45-60 secs...kind of like the a/c just unloaded...only a lot more noticable. I have had the TST on 1/0, but is there any chance that is causing the code? I disconnected and reconnected them tonight and then reset the code. Before that, the TST has been on there all summer and never a code.
Second, isn't the CP3S3 supposed to be better than the CP3? When I climbed under the front end to disconnect and reconnect the harnesses I noticed that there was a residue (very light) on the front of the oil pan. My first thought was oil as the gasket has 50k on it and the heat/ cold expansion. But, when I reached my hand up to the timing and crankshaft sensors I noticed a little more fluid. I smelled it and it was diesel!! I just had the CP3 replaced at 38K for the CP3S3...and now it is doing the same thing. I checked all my hose connections from the FASS, and they are dry, so I know it is the injection pump. I guess that could explain the surge too.
Anyway, any ideas on these items? Anyone else with the TST (R-37) have this problem? I guess the injection pump will have to again be replaced with the extended warranty. I will try to post a pic of where I see the fluid on the injection pump.
I see you are running the BDDL. If it is adding timing, that may be where you are getting the code. I use to have the Rokktech sensor on with the TST. In the colder weather, if I pushed it before the engine was up to operating temp I would get the 336 code. Since removing the Rokktech sensor, no codes. It may be just a timing issue. When the weather was warm, there were no issues.
Thanks for the replies. I have not used the BDDL for about 2 months now....so that shouldn't factor in. I just have the TST on 1/0 both times, and it was up to temp. The first time was after stopping to fill up after 2 hrs of interstate driving, and the second was sitting in the drive 3 days later idling after the 30 min. drive home from work. Kind of odd I thought, but if it has been noticed by others I won't get too upset.
As for the diesel...well the first time I noticed what I have now it took about 5k miles before it poured diesel all over the ground. I guess I will have to take it in and let them look at it.
Still no luck with the diesel fuel...but it hasn't gotten any worse.
I can say you guys hit the nail on the head on the trouble code. I turned the TST to 0/0 and let it idle yesterday morning before work. No code when the high idle kicked in. It was 7* out too. When I started the truck at work I put the TST on 1/0 and let the high idle kick in. After 5 minutes I went back out to the truck and had the trouble code. It was about 20* outside then.
