Car engine management system Chevrolet Aveo 1 (T200)

The control system consists of sensors that provide detailed information about the state of the engine systems, an electronic control unit and actuators. Here are articles on repairing the 1.5 liter SOHC engine management system.

Manifold Absolute Pressure (MAP) Sensor
The manifold absolute pressure (MAP) sensor detects changes in intake manifold pressure resulting from changes in engine load and changes in vehicle speed. The...

Supply Air Temperature (IAT) Sensor
The supply air temperature (IAT) sensor is a negative temperature coefficient thermistor. The sensor resistance is 4,500 Ohm at 40 C, and 70 Ohm at 130°C. The...

Coolant Temperature Sensor (ECT)
The coolant temperature sensor (ECT) is a thermistor (a resistor with a value that changes as the temperature changes) with a negative temperature coefficient...

Engine Oxygen Sensor
Oxygen sensor (O2S) (for unleaded fuel only) Three-channel catalysts are used to control the content of bicarbonates (HC), carbon monoxide (CO) and nitrogen...

Throttle Position Sensor (TP)
The throttle position (TP) sensor is a potentiometer connected to the shaft throttle position sensor on the throttle body. The throttle position sensor circuit...

Knock sensor
The knock sensor detects abnormal engine knocking. The sensor is mounted on the engine block near the cylinders. The sensor produces an AC output voltage that...

Crankshaft position sensor (CPS)
The direct ignition system operates with the help of a magnetic crankshaft position sensor. This sensor protrudes from its mounting socket by approximately 1.3...

Camshaft Position Sensor
The camshaft position sensor sends a CMP signal to the engine control module. The ECM uses this signal as a timing pulse to fire the injectors in the proper...

Control unit (ECM)
The Engine Control Module (ECM), located under the passenger dash, is the control center for the fuel injection system. It constantly monitors information from...

Comprehensive diagnostics of engine components
Comprehensive component diagnostics are required to check the powertrain components for intake and exhaust. Intake Components The intake components are...

Engine ignition system
This ignition system does not use a breaker-distributor and coil. Instead, it uses a crankshaft position sensor that sends a signal to the engine control...
