PicoScope 7 Automotive
Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.
The BIG clue here is "each cycle of the ignition" This job does not need a scope, just yet !!p0235 Boost Pressure Sensor Circuit and P0069 Barometric Pressure Sensor Circuit.
They appear each cycle of the ignition.
I am now assuming that your 5v and Ground Checked out as Ok - Have I got that right ?I rechecked everything. 5v supply, ground. There was no short to ground on signal wire
Shorted up to B+ or Negative ? Either way how did that not manifest itself at the MAP sensor ?I noticed that pressure sender for ac uses 5v also. when I took closer look it turned out that it was shorted
