Wrench symbol=limp home?
Today, on the highway at about 80, tranny almost seemed liked it slipped a little. Wrench symbol came on. Stayed on while doing 70-80 for the next two miles. Got off the exit, I drove normal for the next two min, parked the truck and went into my USCG class.
I brought the owners manual in with me, and it says the wrench means it is an accelerator sensor malfunction, and to bring it to the dealer. Well, I had a break in the morning, no wrench, drove fine.
Went to lunch, no wrench, drove fine.
Drove home on the highway, 70mph or so, no wrench, drove fine.
About a month ago, after I got my FICM replaced at the dealer (along with all new flashes to PCM, TCM, and FICM), I had a similar incident. I was coming back from snowmobiling in VT. Had my sled in the bed of the truck, not in tow mode. The tranny did this same hiccup/slip once maybe twice during that ride, but no wrenc symbol.
Should I be concerned, I feel like I should be? Is this a sensor that is ready to quit on me and leave me stranded? Truck hasnt missed a beat since my FICM replacement.
See my sig, no tuner. EGR delete- including sensor.
I searched for limp mode issues, all that came up were guys that were restricted on speed, or stuck in a certain gear etc.
