After picking the codes on my 92 XJ I got a code 36 (36 Wastegate control circuit open or shorted) sorry no turbo here... Searched Google and found that it could also be an Air Switch Solenoid code. Heep is a stock 4.0, auto, NP231 233K. I've scoured the Haynes and Chilton manuals and Googled this damn thing. Anyone know what this Air Switch Solenoid is?
The Air Switching solenoid is only used on engines with Air Injection, like the 5.9l TBI Dodge. It switched the diverter valve from upstream to downstream air injection.
