Can someone please, tell me what DTC P0667 means?
These last two years have been financially devastating for us. Fortunately, I still have an excellent credit rating, so I've been able to borrow to stay afloat. Today, I am 120 miles from home trying to bid on a job and I certainly don't need any truck problems, but looks like problems will follow me wherever I go. :frown2:
Last night around 11:30 PM the outside ambient temperature here was around 50 Degrees. I started the truck in a hurry and didn't even look at the glow plug light. I turned the key and released it too soon and the engine didn't start, so I did it again and it started without any problem. By the time I got to the end of the 150 ft driveway, the check engine light came on. Since I had to get some sleep, I continued and drove 2.5 miles to my mom's house. It was late and I had to get to bed, so I didn't have time to check for codes.
This morning the temperature was in the mid 50's. When I went to start the truck, the Glow Plug light would NOT go off; after about 10 seconds, I turned the key anyway and stated the engine (Normally the glow light goes off in about 3 seconds at these temperatures, but not today.) The engine started fine and ran fine, but the CEL was ON again. I did notice the Volt Meter was reading around 10 volts. This is the way it usually runs for about 5 minutes or so while the intake air heater is running.
I drove for 1 mile and shut it off. When I turned the key back ON, the glow plug light came ON again. Normally after the engine has run this long (10 minutes) in these temperatures the Glow Plug light does not come ON again, but it did this time. After about 5 seconds, I went ahead and cranked the engine and it started, but the CEL is still on.
I drove another 2 miles to the job site and shut it off.
Now, this afternoon I used my code reader and it says I have (2) P0667 codes, one is pending and the other set the CEL ON.
Here I am trying to bid on a new contract and this truck decides to balk and give me some more crap to worry about. I cannot find any information about DTC P0667, but I'm sure is has something to do with the glow system.
Do the glow plugs normally continue to heat up once the engine has started?
I sure hope I haven't melted one or more glow plugs. I definitely cannot afford ANY major repair expenses at this time. If this requires a major tear-down, I'm out of business. I simply can't borrow that much money to fix this damned thing.
Should I try to find a local GM dealer and try to see what the problem is and try to get it repaired out here at some unknown dealer, or can I wait 'till I get home in a couple days to take it to my GMC dealer?
This is freakin' amazing. For the first 5-year and 65,000 miles the truck ran early flawless. I had ONE claim to replace an ABS sensor and hub assembly on the very last day that my 5-yr/ $0 deductible Extended Warranty was in force and GM covered the repairs. GM wanted another $2800 to extend the warrant another 12 months, but with $100 deductible. I couldn't justify that expense, so I figured that since I had practically ZERO problems for the first 5-years and 65,000 miles, I could risk it and not spend that kind of money up front, that I didn't have.
Not long after the warrant expired, the engine went on LIMP MODE and it cost me $47 for the dealer to diagnose and clean a dirty MAF sensor.
I finally get the truck paid off and now THIS ! ! !
I sure don't need any more of this crap ! ! ! ! :mad2:
Sorry for venting my frustrations here.
Your suggestions and ideas are greatly appreciated.
Thanks.
