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

Supply air temperature (IAT) sensor
Supply air temperature sensor (IAT) is a thermistor with a negative temperature coefficient of resistance. The sensor resistance is 4,500 ohms at 40°C, and 70...

Temperature sensor, coolant (ECT)
coolant temperature sensor (EATING) 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 hydrocarbons (NS), carbon monoxide (SO) and nitrogen...

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

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

Crankshaft Position Sensor (CKP)
The direct ignition system works with a magnetic crankshaft position sensor. This sensor protrudes from its mounting socket by about 1.3 mm relative to the...

Camshaft position sensor
The camshaft position sensor sends a CMP signal to the engine control unit. The ECM uses this signal as a clock pulse to fire the injectors in sequence. The...

Control unit (ECM)
The engine control unit (ECM), located under the passenger panel, is the control center for the fuel injection system. It constantly checks information from...

Comprehensive diagnosis of engine components
Comprehensive component diagnostics are required to test powertrain components for intake and exhaust. Intake components Intake components are monitored for...

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