A question was asked about what signals are preset in the LPG injector driver module. This video tries to answer that question and what can trigger an E-35 code

Thank you so much for making this very informative video. Mine is very intermittent but I will keep looking until I find the issue. Still wish I could find my obd port.

Sounds like a cam or crank shaft sensor. On the cat,Mitsubishi/nissian/unicarrier u have to use oem sensors.

On k21 or k25 unicarriers or nissan lifts always check the ecm grounds to the frame especially the one on the left footwell. Rust and even sometimes painted ground port can cause it to code out. Take a wire or sanding disc and expose the metal.
