GPR Shunt

It should be 0.66 volts or greater. You should be able to measure that with VOM from center stud on GPR to end of shunt stud where sensing wires are connected with GPR on. Rog, try new shunt and if that fails to solve the issue give me a call. We can throw a couple diodes in there (center stud to sensing wires ) which will give each side a 0.70 volt drop to try and fool PCM. http://www.gemstategymnastics.com/at...3%20Diesel.pdf

The issue is more about using the system with the stancor relay.
Its not a plug and play install.

Resistors.
It can be done but you have to access the wiring at another location due to the excessive heat at
the GPR. I would spend my time on a correct install. Its less work.
