I have three codes showing.

0237 - turbo boost pressure sensor low
0606 - internal ECM Processor
0243 - ? (it's not 0234 - over boost)

First, does anyone know what the 243 code is? Second, what would cause any of these codes?

Thanks for any help or direction you can provide.

 

Ok, so cycling the key apparently does not show all the codes. I plugged in a SMARTY and it gave me 5 codes instead of 3. I unplugged the Juice and the mp-8. I still have two codes. I know why I have one, but the other I don't know. It is giving me a "map sensor voltage too high" What would cause this, anyone know?

 

The database I use defines:

P0243 Generic Turbo/Super Charger Wastegate Solenoid A

Maybe the Wastegate Solenoid is stuck, bad, has wiring harness problem, etc. Oops, maybe not using the OEM solenoid, do you have the jumper on the electric solenoid connector, I assume you do not use it with your turbo??

 

I don't have the jumper plug and that's why I said I know why I'm getting one of the codes. The code I'm worried abput is the one for "map sensor voltage too high." I don't know if my map sensor is going bad or what. i have read that multiple things plugged into them can cause them to go bad, but I don't really want to spend $115 on a new one and nothing change.

 

Sometimes if you get too aggressive with remapping the MAP sensor you can get this code. You might see if there is an update or a newer flash for your MP8 as I have heard the TS boxes are very aggressive with the MAP signal.

 

I unhooked the Juice and the mp-8 and then cleared the codes. So with no boxes hooked up, I still got the code.

 

Ok, lets start with the basics.

If you remove all electronics you are getting this MAP sensor voltage high code. Or with the electronics for that matter.

I see you have an aftermarket turbo. After you clear the codes does the code come back immediately on the next key start or only after you drive it?

My next idea would be that one or both modules are having a boost fooling problem and with your aftermarket turbo you are just not getting boost fooling?

Hang in there we will get it fixed.

Thanks, I really appreciate your help on this, seeing that I currently don't even have one of your products on my truck.

I cleared the codes, started the truck, and after it idled for about 10-15 seconds, the codes came back. The wastegate regulator code - since I don't have a bypass plug, and the MAP sensor high voltage code. This is with neither box plugged in, so it shouldn't even be trying to boost fool. As I'm typing this though, I just remembered that ATS sent me a wire in boost fooler trying to solve my wastegate code, and I still have that wired into the stock plug wiring. I'll remove that tomorrow after work and grease up the plug and see if the codes come back after I clear them again.
