NO I DID NOT HAVE A DEALER FLASH THE NEW OR OLD PCM. THE NEW PCM WAS FLASHED BY THE COMPANY THAT I BOUGHT IT FROM.

AS I ALLREADY STATED THE SENT THE NEW PCM BACK TO THE COMPANY THAT I BOUGHT IT FROM & THEY RECHECKED THE PCM & SAID EVERYTHING WAS WORKING FINE.

ALSO AS I STATED I HAVE HAD BOTH PCM;S IN THE VEHICLE SEVERAL TIMES SENSE ALL THE WORK WAS DONE.

I AM TAKING THE SCOPE READING ABOUT 4 INCHES FROM THE SENSOR, & I DO NOT SEE HOW THE PCM COULD BE CAUSING THE PROBLEM OF PART OF THE SQUARE WAVE DROPPING OUT.

I HAVE GOOD VOLTAGE & GROUND GOING TO THE CAM SENSOR & I AM READING THE SIGNAL, THE SQUARE WAVE COMING OUT OF THE SENSOR.

YOU WILL HAVE TO EXPLAIN TO ME HOW THE PCM IS CAUSING A PROBLEM WITH THE CAM SIGNAL, THE SQUARE WAVE, BEFORE THE SIGNAL GETS TO THE PCM.

THANKS AGAIN JOHN
