intermittent tcu code 25

I know this is for the engine torque signal. It only pblinks the code like every 4 start ups from off. Any insite n why it would come on like this. The car drives fine except when it comes on it has a slight 1st to 2nd hard shift like the A solenoid behind the battery is unplugged.

Re: intermittent tcu code 25

Funny you should post this...As mine is doing the same thing now w/ my 4.44

I do remember the engine torque control and a conversation I had w/ someone saying the QC would be the cause of that.


Thoughts?

Re: intermittent tcu code 25

Okay, check to make sure all your QC wires are connected and the ends are wrapped as to not touch any metal. This code is usually caused by a link between the TCU and ECU aka, the QC.


I will be doing that if I am still alive after this big Tor-Con 9 Indiana storm.

Re: intermittent tcu code 25

I actually just checked the wiring for that also to make sure that they were tight. This is on the pearly i just picked up. I used pliers to retighten them to be safe and started the car several times with no light so we will see what happens. I never had this problem on my red one with the qc. If anything I may just sauter them together instead of the quick connects.

Sounds good. Maybe we can get Harvey to spill the beans on this?

Re: intermittent tcu code 25

I think it was a bad quick connect. I really don't care for them. As for it throwing a code could be because one of the 2 wires you split may go to the torque control? Overall no codes so far but ill be keeping an eye on it.

Re: intermittent tcu code 25

Hope that is all it was. It's hailing here right now so I can't go check, even though it's bugging the crap out of me.

When you turn the key on, the TCU does a system check.
Sometimes the electrolytic capacitors in the QC are charging at the same time, and the TCU pulls the code for the Torque Control.
It does not affect the way the TCU or the QC work.

Re: intermittent tcu code 25

Thanks Harvey. I still think it may have been a bad hookup on the wire. Still code free.

I've got the same problem, going to check my QC connections this weekend if I can find it. No other codes, just the exsisting 25 every 4-5 starts
