Welcome, I'm Chris (aka-Moose).

  • THE TIME I AM ONLINE, 7 days a week normally online around midday and then late evening until early morning.
  • PHONE CALLS are automatically offered by the website normally after my first reply. I complete calls where I feel it is a benefit.
  • UPLOADED LINKS I SEND, if I upload dropbox links, they will open on a home PC, often they fail on a work PC, on a phone use the box on the top right of your phone screen for direct download.

Is this a 2.0 or 2.3 engine?

Are you getting the same results when testing the CMP sensor?

Do you get the same results at the sensors and the PCM even with the sensor unplugged?

Here is a wire diagram if needed https://www.dropbox.com/s/2wu0td8sklzypeq/20mazda.png?dl=0

same think
Mazda Mechanic: Chris (aka- Moose), Technician replied 4 months ago

If you are getting no power to the sensors from your PCM then your PCM is faulty or the PCM is not getting all the powers and grounds it needs to operate correct, power up all sensors in return to get a reading from them. Do you need the PCM wire diagram to check all the PCM inputs?

You now will see a rating scale 1=bad to-5=excellent because I have posted a full or partial answer instead of an info request. When you rate I get a portion of the deposit you made, no rating means you still paid, but I earn nothing. My goal is understanding your question, and addressing it in full detail. In return, receiving a 5-star rating. Rating does not close the post or stop the conversation. Please keep in contact and reply as much as needed. Thanks, Chris
