So, last week sometime, driving down the street my truck starts sputtering and CEL comes on. Checked the codes, got the P0300 and P0339. I remembered from this forum that when you start getting a sputtering truck especially under acceleration then crankshaft sensor or EGR valve could be the issue. So i ordered the sensors off rockauto (EGR and crankshaft position sensor) and replaced them today. EGR is easy, just 4 bolts. I looked all over for a picture of the dang crankshaft sensor location, but wasn't successful. Eventually found a diagram online, but I thought that I would post up a couple pics for people looking for it in the future.

This is what the new valve looks like.


Here is where its located, you can see the wiring harness in this picture, and on the left is the oil pan. Its on the passanger side to the back of the engine block.


Here's a closer pic of the sensor


It takes a 10mm socket nicely, i used a 3 inch extension. It was easier to get the little orange piece out and get the wiring harness off once I got the bolt out. I had to get some pliers to pull the old sensor out, there's not a lot of room to get your hands in there.

Stick the new one in and put the wiring harness back on and you are good to go. Lucky for me my problems are solved, no more sputtering and CEL is gone. I know this is not a hard fix, but there is a dearth of here was my CEL and here is my solution posts on here, and I thought I would post for future people.

 

Good info. Thanks.
