This process is controlled by the onboard controller.
The onboard controller considers the fuel mixture leaned.
If they are correct,the fault may be in the onboard controller.
Based on these impulses, the onboard controller controls the fuel injectors and the ignition system.
If they are correct,the fault may be in the onboard controller.
The onboard controller responds much quickly to a digital signal, because it is not necessary to convert it to analog.
If they are correct,most likely reason is the onboard controller itself.
By using the speed/density method, the onboard controller calculates the fuel mixture composition depending on the signal of MAP and engine speed.
If they are present and correct,the reason may be the onboard controller itself.
If there is no voltage on terminal coming from the onboard controller, you should check the signal wires between the sensor and the onboard controller.
Check the integrity of the signal wires between the sensor and the onboard controller.
NOTE: If the MAP sensor is located inside the onboard controller, verification of the output signal is impossible.
It can be located in the engine compartment as a separate component or integrated in the onboard controller.
During the engine rotation the sensor sends a signal to the onboard controller whenever the first cylinder is at the top dead center(TDC).
These sensors can be located in the engine compartment as a separate component orcan be integrated into the onboard controller.
TPS gives to the onboard controller information about the idling, deceleration, rate of acceleration and the fully open throttle valve state(WOT).
Every time the magnet passes through the sensor, its magnetic field is changed andthe resulting pulse is sent to the onboard controller for processing.
Currents flowing through the oxygen pump,set by the onboard controller, depend on the value of the deviation of the fuel mixture from the stoichiometric.
When the slot passes the coil, it is excited bythe mutual inductance and a signal indicating the position of the first cylinder is sent to the onboard controller.
In simultaneous fuel injection systems, the onboard controller does not identify the cylinders and the firing order, because this is not necessary for the system to operate.
When there is a high level of vacuum in the intake manifold(e.g. idling),MAP output signal is relatively low and the onboard controller provides less fuel.
The onboard controller generates very high frequency(between 150 and 2500 cycles per second) to the exciter coil, which is located near the rotating disc.
This current also flows through a calibration resistor andforms a voltage drop which enters the onboard controller for calculation of the quantity of the injected fuel.
If the supply voltage and/or ground are bad,you should check conductivity of the power supply and/or the ground wires between the MAF sensor and the onboard controller.
If all wires are correct, butthere is no output voltage from the onboard controller, you have to verify all power supply and ground connections of the onboard controller.
The onboard controller generates electric current and supplies the oxygen pump, value and polarity of which provides keeping the sensitive element of the sensor to a set level(450mV).
By analyzing the level of the output signal, the onboard controller reads the variation coefficient value of the fuel mixture composition, which in practice is the lambda coefficient.
The onboard controller receives signal from the oxygen sensor, compares it with a value stored in its memory and if the signal differs from the optimal for the current mode, it adjusts the fuel injection duration in both directions.
This will not generate any fault codes(if the onboard controller is not programmed to detect voltage changes) since the sensor continues to operate within its design parameters.
In this case the onboard controller considers the oxygen sensor correct because after the engine has been started and warmed, the sensor have lead away the reference voltage and lowered it to~0V.
