Question about Ford F-350

My truck is an '08 Ford F350 with the 6.4 diesel. Got the P2002 and P2463 codes the other day. In addition I got "reduced engine power" on the message center. Any ideas?

    Truck is bone stock. The p2002 code has come up a time or two but reset on its own. This time it was accompanied by the p2463 code and a "reduced engine power" message. The truck won't go over 45mph.

    The truck is clean as a whistle and with only 11k miles. Whats your take on the P2463? It tries to go into regen but only for a few seconds to minutes.

Hi

These codes are both related to the DPF on your truck

P2002 = Diesel Particulate Filter Efficiency Below Threshold (Bank 1)

P2463 Diesel Particulate Filter Restriction - Soot Accumulation

This filter device is designed to remove diesel particulate matter (soot) from the exhaust. When it gets blocked up with soot it throws these codes and puts your truck into 'limp home mode' - hence the message about reduced power.

To resolve this you will have to change the particulate filter and have the codes reset by an OBD scanner. This will resolve the problem.

Hope this helps. Please do rate my answer. Many Thanks.

P2002- Diesel Particulate filter efficiency below threshold. Chances are you're using an aftermarket CAI. Basically it's saying that the truck is breathing better than thefactory intended. I get the same code w/ my truck for about the 1st 350miles after a regen, then it doesn't return untill after the next regencycle.

Regarding "reduced engine power" message: get a good can of throttle body cleaner and take off air intake you canspray the throttle body from there and use a rag to wipe the crud offalso open the throttle blade with your finger and get the stuff off ofthe back of it and where it seals or you could just take it off it'snot to hard to do that either. Since you cleaned the throttle body, you should disconnect the batteryfor about 30-45 minutes to let the PCM reset back to the factorysettings. Might run even better, as the PCM has been changing it'ssettings to keep the engine running well with a dirty ThrottleBody.....right now, the PCM still "thinks" the Throttle Body is dirty.

Hi,

The codes that you have :-


P2463 - Particulate filter restriction. soot accumulation
Solution - Try to change the exhaust filter and check if this could fix the code.

The particulate trap is built into the exhaust, and "holds" emissions particles that can damage the diesel catalytic converter until they can burn up small enough to not cause any damage.

Most likely, the exhaust you installed simply isn't compatible with the on board computer system on the truck. Until this engine exists long enough for reliable aftermarket parts to become available, you may need to revert back to the factory exhaust.

This "particulate trap" technology is still very new, and unfortunately alot of aftermarket systems either aren't aware, or haven't yet done enough testing to produce proper parts for these vehicles.
Solution -
if you convert back to the stock exhaust will that stop this error code.
Hope i helped.

Thanks for using ' Fixya ' and have a nice day!!

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

Need to fix my 2007 Dodge Ram 3500 dually,6.7 Cummings diesel, check engine light code P2002


P2002 - Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
Description: The powertrain control module(PCM) monitors the efficiency of the diesel particulate filter for a concern. The efficiency of the filter is determined by the amount of restriction in the filter for a certain exhaust flow rate. The diesel particulate filter is preconditioned for 5,000 km (3,107 miles) before the PCM begins to monitor the level of restriction. The test fails when the measured level of restriction is less than the expected level calculated by the PCM. Possible Causes:
  • Dirty air cleaner element
  • Recent manual or thorough diesel particulate filter regeneration
  • Aftermarket accessories and performance modifications
  • Modified tailpipe
  • Exhaust leaks before or near the diesel particulate filter pressure sensor
  • Leaks in the diesel particulate filter pressure sensor connecting hose
  • Damaged diesel particulate filter
Diagnostic Aids: Check for leaks in the exhaust system. Check for aftermarket exhaust accessories and performance modifications that decrease the exhaust restriction. If a new diesel particulate filter was recently installed, verify the diesel particulate filter parameter reset procedure was carried out.

this is a complex car, and engines.
Just 1 code? and no pendings?
A DIESEL engine , and in USA , are ya> or in Canada?

the shop manual for all complex cars, is a must have.

P2 codes are factory codes, unique to only Suzuki ,
so use their books.
alldata dot com has it.

"Particulate Trap Efficiency Below Threshold Malfunction "
but cleaning it , is not the only way to fix it.
the manual covers this, and how the test works and what can make it fail, simple swaps or cleans dont always work.
RTM please.
