[V8] Testing RPM Sensor

[Jeremy Ward]

Hey Eric, welcome to the list and to V8 ownership!

I did a write up on how to change this sensor, which can be found here:

Hope this helps!

Cheers,

Thanks for the help guys!

I pulled the codes, and it was giving me the code for the RPM sensor (2111),
however my car will not start and according to the documentation that I have
(http://www.sjmautotechnik.com/trouble_shooting/ecufv8.html#fcthree)
sometimes when the car will not start and you pull codes 2111 will come up.
Does anyone out there have any experience with this?

I have not had any hot start issues with the car, but I have only owned the
car for a couple of weeks now. What else could cause my problem? I am
missing spark from both sides of the engine.

Thanks again for the help!
