Toyota 7FGU35:
check engine light

We received the machine with a seized engine. After replacing the engine, when the throttle is used the engine stays at idle and the engine light flashes but disappears when you lay off.
It's the electronic throttle dual fuel set up.

Any ideas?

yep cat trucks do the same thing when the plugs get worn and gap increases beyond the ECM's capability to compensate for it.
Code E27 i believe

but i've never seen a gm v6 do it before. I guess its possible though.

I have seen worn spark plugs with a wide spark gap cause Nissan (1F1 series) forklifts to code out for the Crank/Cam sensors so it sounds very possible......

How in the world did you find that one? I'd never guess that spark plugs would cause a check engine light

Hi guys, sorry for the delay. As it turns out my guys overlooked the spark plug gap (apparently).
I didn't think that would code an engine but it's all good now.
Thanks for the input...

what i meant was that if this is a new engine, the ecm must be tuned to the old engine, putting a new engine in certainly will require having to relearn the ecm.

Or does this truck not have the Tier 1, 2 or 3 system on it? I suppose i may have spoken out of turn without asking that information first, it could be pre-tier engine maybe?

How many blinks? I have not heard of recalibrating on those trucks. If you used the old carburetor it could be the switches that tell the computer where the accelerator lever on the carburetor is. I have had them mess up and put the truck into limp mode.

Swoop- I'm unfamiliar with recalibrating an engine after a replacement has been installed- how is it done & is it always neccasary? Do you know if this is an issue with other makes? I appreciate your patience.

so this new engine is exactly the same model engine you pulled out?
has the same sensors?

if so all you may need to be doing is recalibrating the engine
relearning the throttle pedal, throttle assy and fuel system air fuel mix ratios etc.

just a thought

Engine is the GM 4.3 and we refit the original distributor from the old engine

What engine is in the lift & what distributor did you install?

I would check the throttle pot under the accelerator pedal.
