5) The malfunction phenomenon and the judgment method
(1) The fault phenomenon: can not enter the idle state; or step on the accelerator, accelerate the
powerless;
(2) The cause of failure of internal short circuit or open circuit: sensor; or throttle body to the engine
control unit Connection or short circuit breakers.
(3) Note: repair is not removable solar term door position sensor
(4) A simple method to measure
The power supply voltage measurement sensor A and B ends of the 5V;
Resistors A and B ends of the value is about
Signal C solar term door idle position of voltage between 0.3~0.7V;
Signal C is fully open when the voltage to ground between 4.05~4.75V.
