I have a 2017 Mazda CX-5. The ftp sensor has 2.6 volts output at the sensor but the scan tool shows 0 volts. I am getting a p0452 code. I’m using an Otofix d1 lite scan tool. Where should I look next? I can’t find any wiring diagram on google.

There are only two possibilities: the engine control module is not logical or there is an open in the wire causing the signal not to make it to the PCM. The latter is the most possible. Hopefully, you will get a wiring diagram that can help with the issue.
Assuming is never a good thing.

Does anyone have access to a wiring diagram to verify the PCM pin connection to the Fuel Tank Pressure Sensor? I think it goes to pin 2Y. Is that correct?

2AJ with coolant control valve, 2Y for without coolant control valve and there are 2 connectors from sensor to PCM. See attachments.

Thanks for the diagram but the wire colors don’t match. There was no gray wire . The brown wire was the only color correct. Do you have any other diagrams for 2017 Mazda CX-5 2.5 engine py?

Thanks for the diagram but the colors don’t seem to be correct.
