Sound like it isn't working at all, which terminals in plug are you checking, think 17 and 11 are the ones to check, terminal 30 is control voltage which would be 4.9 volts constant, you can also do a resistance check between 11 and 17 as it has a open circuit at closed throttle then a smooth resistance increase from just open to fully open throttle.

No bud as thought it would be better to go straight to plug itself. if im getting the 4.9volt on closed throttle then i must be testing it right. I just need someone to confirm im ok to check voltage from plug rather then ecu
