Best Way To Diagnose Limp Mode?

[fastfwd]

Hi all,

I have recently replaced the turbo, new front mount, new piping. Basically had most of the induction and exhaust apart. I have put the car back together and its running but it goes into limp mode.

Car wont throttle over 2-3000RPM, I figured I forgot to plug in a sensor. Went over all of the sensors and made sure they are plugged in correctly. All look fine.

I have a SCT Chip with hand controller. Tried looking for the ecu to plug the hand controller into see if it has a diagnosis function to see what sensor is the issue but I couldnt find the ECU.

Does the hand controllers have diagnosis settings? what would be the easiest way to diagnose this.

Got a tune in the morning and need to sort it out before then. :(

Did you change injectors?

OBD2 Diagnostics plug is located under the steering column basically in front for you RH need behind the fuse Panel.

I have different injectors but I didnt change them this time round. Was done on a previous tune.

Ok found it and did a "read dct's" under check engine settings. I figured day's were the sensors. This it the error.

Is this the pressure sensor?

If one leg moves slower than the other you are in limp mode my friend

Thanks mats

Anyone know what this code is referring to? Need to find what sensor this is.

Boost presure sensor. Lives on the under battery pipe on B series Sedans dunno where it leaves on Terris. Somewhere between the cooler outlet and throttle body.

Yeah was like I thought pressure sensor. Don't know but there must not been something wrong with the hose I used. Got it working. Cleared the limp mode and reset and all good
