View Full Version : My engine light just pop out!

January 30th, 2009, 02:02 PM
Hey Guys, every since i got my truckhttp://images.intellitxt.com/ast/adTypes/mag-glass_10x10.gif (http://forums.trailvoy.com/showthread.php?p=668504&posted=1#) back Ive been having many problems that have not occur before my accident.

Here is what we changed, changed air filter, spark plugs, efans, hid headlights and fog lights, throttle body cleaned, fuel injector clean, oil change, 22 gal tank (only the tank and the fuel lines that was changed).

But now Im getting several problems such as:

1) -.7 decrease in gas milegage
2) stalling or hesistation problem when shifting from 1 to 2(fix the pedal problem thanks to Erik's tune)
3) electrical problem
4)engine light (after this showed up ive been having problems moving the truck as if it lost power.
5) On of the bulbs for the HID blew out and I just got them.
6) the dome lights keep popping out when we configure the DIC to turn it off
7) My engine light just lighted up
8) The Battery reader on the DIC keeps swing over and under 14.

Why is this happening?

Ive also have been getting these problems shown on efilive

The first code refers to the transmission, have you cleared the codes yet? If they come back then you're probably going to have to have some transmission work done to replace the shift solenoids. The key ignition circuit is interesting, with my remote start Ive gotten a key in ignition circuit but it was because my bypass module wasnt working properly.

Im wondering if you're PCM is faulty with all these problems you've been having. And all of these issues popped up after your accident? Maybe take it back to where you had it fixed and have them fix it, should be covered by insurance from the accident.

Have them specifically look at the following:
- alternator/regulator overcharging or overvolting;
- PCM as Erik said;
- EVAP system plumbing, solenoids, fuel tank air/vac leak;
- Possible BCM problems;
- Other wiring problems like bad/missing ground connections;

They have to get an experienced diagnostic technician to find the problem(s).

I cleared the code, but it was not the same before the engine light came out, a lil improvement though. and yes everything occurs after the accident.

so you basicly want to cut this part out only from this to this?
