Santana's fault code in 2008 is not credible.

The fault code of the old Santana throttle potentiometer signal in 2008 is not credible for the following reasons:

1. Because the timing of intake valve and exhaust valve controlled by crank angle is inaccurate, that is, the intake and exhaust rhythm of throttle cylinder controlled by crank angle deviates from the rhythm of mixed gas combustion in cylinder, resulting in insufficient gasoline combustion and affecting the normal output of engine power;

2. Black deposits on the inner wall of the throttle throat lead to insufficient air intake in the engine combustion chamber or accidental seizure of the butterfly valve at idle speed. Clean the throttle valve. When cleaning, remove the throttle valve from the engine intake pipe and clean the side near the engine.
