PO 127 Error Code

[Poppa Dawg]

I had this code come up today on my RXT-X. I had the EXhaust temp sensor out the other day & dropped it on the floor so don't know if it got damaged. Called a couple of people but this code number is not in the older resource books. I measured the resistance across the sensor & it appear to measure approx. 1125 ohms. Has anyone seen this code or have access to find out. I don't think it is in the manual that comes with the boat but I can't find mine.

Maybe someone can measure the resistance across their sensor & see what you measure. Thanks.

Water box 2100 ohmagiz

Can someone tell me what this code is? I did a search and couldn't find anything. I am suspecting it is a low airtemp sensor code

PO 127

Intercooler system fault.

High air intake temperature. Fault detected when engine is running and stopped. Blocked intercooler circuit.

The code that was thrown on mine back then was caused by a bad sensor ( the one in the front of the intake manfold).

Hmmm Thanks for your help. That is NOT what I was expecting. I will try a new sensor first, since I am pretty sure my airtemps are cool.

I copied it right out of the manual....

Whatever Cal, by now you are probably running about 100 with an ALU manifold. You know that sensor cant tolerate all that!!! hahaha
