2009 that set p2453 intermittently

Steve Mutter · January 29, 2015

I have a 2009 f-350 that set p2453 p2463 p246c. I performed the pinpoint test for p2453 and it leads me to replace the dpf pressure sensor. The problem is I already replaced the pressure sensor last year for the same codes so I don't think I fixed the problem. The pinpoint test is not really good so I checked for wire chafes at the harness near the fuel cooler pump and checked the dpf sensor connector and pins, all look good. Has anyone seen any other chafe points or run into bad dpf sensors causing these issues.

I had a DPF pressure nipple completely plugged with carbon once. I don't remember what code it set though.

Checked the tube and found it clear, going to do do some more looking tomorrow

I take it TSB 12-06-08 and 09-16-08 have been done or do not apply...my guess is "No" since you have a DPF sensor performance code. Did you check the cab pull connector C110 @ the LF fender terminal pin fit or terminal. What is the FF on the P2453, going down the road, hot or cold....?
