Going mad did a ODB p1688 and p0107 motor ligth

Hi my car 05 base 192hp. It had loss of power half a mile after workshop had it in

I stopped at once got the car towed home. Then did a ODB2 test got p0107 first. testet the sensor and it was a bit strange on the ohm test. So just got one new.
by the way when i took of the conector the car got power back. thats aslo why i change it,
I did a new test then clean it. Let the car run and checket it on the Bluedriver odb it was perfekt gor warm.. so tok it for a lille one k drive and back home. No codes.

the next day the light came back motor.. and little the red coolant light. So i did a new odb test and got p1688 and p0107 up
wow im fed up.. I have clean the map and a new one is on the way i have clean every conector.. Not the OMP yet since i have to under the car for that.
any tips? Happend to anyone else? Been thinking short ore even the ECU i hope its not that.. Ore the wireing. The car has only 75000kilometers on it,
Im waiting for a komp tester. So i can check it, But i do not know never been working on wankel, This is the only car that brand shop have done all the work to not me. But after this i do not trust the mazda shop here anymore. They dont cear!

What does the shop have to say about this? They were the last to touch it. What work did they do and are they not taking responsibility for this?
Is there a coolant leak? The light being on can be problematic.

It's not the ECU. Certainly sounds electrical if it's affecting the MAF and the OMP, but depending on what was touched during service, there might be good reasons those 2 systems are affected.

It sounds like you've been through quite a frustrating experience with your car. Based on the issues you've described, it seems like you've already done some troubleshooting by replacing the sensor and cleaning connectors. Since you're still facing error codes like p1688 and p0107, here are some additional tips you can consider:

1. **Check the Wiring**: Given the recurring issues, it might be worth inspecting the wiring harness for any signs of damage or corrosion. Faulty wiring can lead to intermittent power loss and trigger error codes.

2. **Inspect the OMP (Oil Metering Pump)**: As you mentioned, you haven't checked the OMP yet due to accessibility reasons. The OMP plays a crucial role in the lubrication of the rotary engine, so ensuring it's functioning correctly is important.

3. **Consider ECU Testing**: If the issues persist after checking the above components, it might be worth testing the ECU (Engine Control Unit) to rule out any faults in the car's computer system.

Attached is the factory diagnostic procedure and wiring diagram for the affected parts.
Note that we do not have a MAP sensor on our car.
