This vehicle burns excessively black and when you drive it to distance of 1km, it will begin to surge and off, when you crank it, it will crank but won't but wouldn't start, if it starts but it will not raise.
Then I scanned and detected:
1. P0107: excessively low input voltage from manifold absolute pressure sensor.
2. P2118: Electronic throttle motor range/performance problem.
I have erased and driven the vehicle and it is still throwing back the codes.
Please I need a diagram of that vehicle to first check resistance from ECM to throttle motor and MAP sensor.
Thanks

Hi,

This vehicle isn't offered in the US, so I have very limited information. However, I'll try my best to help.

If you have a low input voltage at the MAP sensor, disconnect it and check to see the voltage signal from the PCM. If you are right around 5v. Try this first and let me know the results.

Focus on the P0107 first, because it is the cause of the other code.

I will watch for your reply.

Take care,

Joe
