Ok first here is a list of the codes

P0340
P0732
P0733
P1211
P1212

I do have a superchips set to the middle level

Truck has a new fuel pump and filter last month

Ok this started about a month ago. I was heading home and my truck just died. If I let the fuel pump prime a few times I could make it about 1/2 a mile before it would die, so I limped it home the last 4 miles.

Put in new fuel pump and filter.

2 days later leaving the job site I made a right hand turn and it died again, but started right up and I had no problems untill now.

Today on the way into work I got about 1.5 blocks from my house and I lost power (not 12V engine power) and the motor started to act like I just started it on a very cold day (rapping bad) and then died.

I then was able to pull the above codes.

I then restarted it and it drove fine all the way to work.

I am getting about 50-100 miles less per tank in milage this summer. (not sure if related)

Also not sure if this is normal but my fuel pump does not cycle off, untill the relay makes it turn off. (with key in on position but not started)


Any ideas? Or is it a dealer thing?

 

I'm sure there are some of the Guru's that will chime in, and I'm not saying this is the only cause of those symptoms but could cause a few of them-Have you tried changing the CPS?

 

I have not tried to change the CPS. I figured I would ask before throwing parts at it.

Thank you for your idea deffinatly one of the things I was thinking.

Also I have had the truck since 130,000 miles and it has 175,000 now.

 

The symptoms you describe are very similar to what my truck has done recently, except for that my truck has not repeated the symptoms since I changed my filter and pump. I have only put about 100 miles on it since new pump and filter so I am not convinced yet. I still have a feeling that something isnt exactly right though so I am interested in any solutions these guys come up with as well.

 

Does anyone know the part number to the "less expensive" CPS? Even with my discount I am still getting quoted in the $200 range.

 

Go to Dieselsite.com, alot of the site sponsors sell them for 22 bucks (about)!

Ok part # F7TZ-12K073-B

Dealer has it for $20

They must have a few of the old ones their trying to get rid of first.

 

Check the oil......

p0340= you need a cam sensor
p0732= 2nd gear is slipping
p0733= 3rd gear is slipping
p1211= icp cant be controlled unresponsive
p1212= icp voltage out of range

the 340 is easy, 15 bucks and a 10mm socket to fix it
sorry to say you need a tranny for the 732 733,
the 1211 and 1212 is normally 1 of 2 things 1st being wore out oil, the second being a corroded icp connector, check those and get back if all is good for more help

 

Well here is the verdict.

I replaced the cam sensor that day.

I have now been problem free for 1 week.

I did investigate the tranny codes and this is what I have found out. When my truck died the last time (and the only time those tranny codes showed up) my truck was in the middle of shifting from 2nd to 3rd gear. That is what caused the tranny codes.

My tranny shifts great, and was refreshed about 50k ago (new TC and just a quick going through)

As for the injector codes, from what I have read here and on other sites, it usualy is caused by aftermarket programers. I had put mine up the the top level for a day after the first time my truck died (only way it would start) and that was when my fuel pump went out. I'm guessing that is what caused the low/high injector pressure.

I'm open to other ideas or short comings in what I think happened.

 

The 1211 and 1212 are not from your fuel pump. Those codes point toward your High Pressure Oil Pump. It could also be from you programmer calling for more oil that your pump can deliever. Could all be from you bad CPS. Clear the codes and run it a see if any comes back.

 

Heres some reading on the subject....From Diesel Mans Page....

Loss of power, usually after a hard acceleration; Rough idle; Check engine light comes on, DTC P1211:
Intermittent high pressure oil leakage.
This condition usually occurs when the vehicle is cold and the oil is thick. When performing a hard acceleration, the truck suddenly looses power, the check engine light comes on, and once returning to idle the engine runs rough and won't accelerate. Cycling the key may correct the concern, clearing the code from the PCM will correct it temporarily. If you can monitor data stream, at idle the ICP pressure normally is 400-700 PSI and the IPR duty cycle is 9-14%; at cruise, ICP is 700-1200 pSI and IPR is 15-20%; under normal acceleration, ICP is 1200-2000 PSI and IPR is 20-30%; and under WOT accel, the ICP is up to 3600 PSI and the IPR is 35% or higher. When the above symptom occurs, typically the idle ICP reading will be normal, but the IPR duty cycle will be high--over 20% and up to the max 50%. A "blow-by" condition has occured somewhere in the HP oil circuit. If you can get the problem to re-occur with some frequency, the most probable cause is worn or deteriorated injector or IPR o-rings. If the problem is intermittent, it could be a sticking IPR valve. Replace the injector o-rings with the latest-level kits--F8TZ-9229-AA. When replacing the IPR, make sure you get the correct part for the build date/serial number of your engine.

KE7 KOER ON-DEMAND DIAGNOSTIC TROUBLE CODE (DTC) P1211

• DTC P1211 indicates that injection control pressure was above or below commanded desired pressure during self test mode.
• Possible causes:
  • incorrect oil or viscosity
  • poor oil quality
  • gel fuel/no fuel
  • low fuel pressure
  • damaged IPR valve
  • high-pressure oil system leak
  • damaged high-pressure oil pump
  • damaged PCM
• Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions.
