My engine was detonating which i put down to shit fuel, it may not be the cause at all, so I've been checking engine sensors. @ 750rpm idle the mas voltage is supposed to read 1.5v,with the ignition on motor not running 0.8v. I get 1.25v @ 750-800rpm and 0.08v not running. I tested three mas's all genuine Nissan, they all read the same. I used three different programs conzult datascan dr300zx all showed the same readings, so I'm ruling out a faulty mas. Anyone else get these readings from there mas?
