What is the fault light of sagitar engine?

The fault light of sagitar engine is on because of engine electrical fault (including air flowmeter, throttle, intake pressure sensor, oxygen sensor, ignition coil, spark plug and other parts) and engine mechanical fault (including fuel quality problem, carbon deposition problem and so on). ).

As follows:

1. Engine electrical fault: This kind of fault includes the damage of some sensors, such as air flow meter, throttle idling motor, intake pressure sensor, oxygen sensor, ignition coil, spark plug, water temperature sensor, crankshaft position sensor or camshaft position sensor, etc. It also includes some control units or actuators, such as engine computer, ignition computer, fuel pump, camshaft adjustment solenoid valve and so on. In addition to these electrical components, the wires between these components may also cause faults.

Solution: Troubleshoot the components one by one and carry out maintenance.

2. Causes of engine mechanical failure: for example, the fuel quality changes, some fuels with more additives are used, or the air inlet, throttle or spark plug are covered with carbon deposits, and the air leakage at the air inlet is lower than the standard value, which will also produce corresponding fault codes. In severe cases, the engine fault light will be reported in the instrument. Chain elongation is common, which requires us to measure whether the chain is within the standard range. If it is stretched, it needs to be replaced.

Solution: Replace the fuel or clean up the carbon deposit, and check and deal with it in turn. Million car purchase subsidy
