Re: CEL - P2290 error code
The van is back.
Dealership performed some tests which returned codes P0611/1378. The service tech correlated this to a Ford TSB 08-26-03, and ended up reflashing the computer. This TSB involves the Fuel Injection Control Module (FICM), which clearly sounds like a possible culprit. So, the codes are now gone and they can't recreate the problem so the problem must be fixed, right? I'm hoping so, but part of me wants to know there was a specific failure and the failed part was replaced.
I've attached a copy of the TSB that I was able to locate. Interestingly, the TSB talks about "An improperly operating vehicle battery(s) or charging system can cause additional operating loads to the internal components of the FICM due to low power supply voltages." I know my house battery was low due to solar panel issues and not driving the van much, but I wonder if the van batteries were getting low and contributing to the error codes? Time will tell I guess, but the reflash was covered under (emissions) warranty with no deductible. The van drove fine on the way home, but I'll need to drive it hard up some hills just to be sure.
BTW, I had both fuel filters replaced ($163 parts & labor).
