What are the fault codes P0337 and P 1607 of Chevrolet Lodge?

English definition:-> CKP sensor A circuit is low.

English definition:-> Crankshaft Position Sensor A Circuit Low

Category:-> shooting system

Background knowledge:-> The function of crankshaft is to convert the up-and-down motion of piston into rotary motion. Crankshaft position (CKP) sensor (also called top dead center sensor) is used to detect top dead center (TDC) signal, crank angle signal and engine speed signal, and input them into the computer, so that the computer can issue the best ignition timing instruction according to the ignition sequence of cylinders. This fault code will occur if the electronic control unit (ECU) detects that the circuit voltage of crankshaft sensor A is lower than the calibrated minimum value.

Fault code: -> P 1607

English definition:-> engine control module (ECM)/ electronic throttle system control module-communication failure

English definition:-> engine control module (ECM)/ electronic throttle system control module-communication failure

Category:-> power system (customized by the manufacturer)

Background knowledge:-> Engine control module, also called engine control unit (in some cars, engine control module and transmission control module are integrated to form powertrain control module), which controls the whole engine. Its main function is to control the optimal fuel injection quantity and ignition timing of the engine. Another important role is the component responsible for monitoring exhaust emission control. In the electronic throttle (ETC) system, the electronic control module (ECU) instructs the throttle position motor to optimize the throttle opening according to the signal from the accelerator pedal position (APP) sensor, engine speed, vehicle speed, air conditioning energy consumption, etc.
