limp mode? how to get out of it
 
so i think i am in limp mode it woundnt rev after the car starts only when at start up, so does using a code reader clear it or does resetting the ecu helps? thanks (no limp mode here guys) it was just some throttle peddle sensor.

also, is the check engine light the engine service soon light sensor on the z? or is it different?

edit: so i didnt do the ecu reset because it didnt need it, but i did do the code reader and found a few codes for it some of it cleared but only 1 keeps coming back after clearing it.. i believe its p2135 something about the throttle peddle position sensor, im trying to figure that out.

does anyone know where the airbag sensor wires are? i try looking for it but dont see it anywhere.

Depends on why it's in limp mode. You should be able to clear it using an OBD scanner. If that doesn't work, reset the ECM.

i have no clue why it it was in limp mode in the first place but from research it woundnt rev right, its like its stuck at that specific rpm.. so it think its a limp mode problem, but either way ill do both!

also the engine service soon light is on and im not sure if thats the check engine light or not. can you tell me?

Yes ... but I'd rather teach you to fish than feed you. If you can't find what you need in the Owner's Manual, check the FSM.

I'll do that later, so the lights means the same thing right?

The OM and FSM will tell you what the different idiot lights mean.

The FSM will tell you what can put the car into limp mode and how to clear it.

i wish it was around 3k too bad it woundnt accelerate up to 1500, like i said when i first start the car it would go up to 8-9k after a few seconds of revving it gets down to 1k and when i accelerate it gets stuck at 1500.. i have a automatic

shut the car off, let it sit for 10-20 min, restart. that got me out of limp mode when the tranny felt the need to put the ECU into limp mode one day. I was able to shift gears in the AT but stuck under 3k rpm.

try that.

i let the car sit for the whole 24 hour and its still the same thing, so now its just sitting taking up space!

hmmm. yup go back to initial comments of hitting it with a scanner and seeing if a code pops. there may be something bigger than just limp mode.

maybe do a reset but unhooking the battery for a bit then reconnect and start up.
