SENSOR




AIR FLOW SENSOR


The air flow sensor is basically the same as the one mounted on the 4B1 engine.

INTAKE AIR TEMPERATURE SENSOR


The intake air temperature sensor is basically the same as the one mounted on the 4B1 engine.

MANIFOLD ABSOLUTE PRESSURE SENSOR


The manifold absolute pressure sensor is basically the same as the one mounted on the 4B1 engine.

ENGINE COOLANT TEMPERATURE SENSOR


The engine coolant temperature sensor is basically the same as the one mounted on the 4B1 engine.

THROTTLE POSITION SENSOR


The throttle position sensor is basically the same as the one mounted on the 4B1 engine.

LINEAR AIR-FUEL RATIO SENSOR



The linear air-fuel ratio sensor is installed to the exhaust manifold. This sensor detects the oxygen concentration in the exhaust gas by a solid electrolyte (zirconia). It can detect the air-fuel ratio in the wide range from the lean air-fuel ratio to the rich air-fuel ratio. The engine-ECU measures the air-fuel ratio by measuring electrical current when the voltage is applied to the linear air-fuel ratio sensor. Therefore, the engine-ECU can accurately perform the feedback control to the air-fuel ratio so that the three-way catalytic conversion efficiency can reach the best theoretical air-fuel ratio.
To activate elements, this sensor integrates the heater. The engine-ECU controls the electrical current going through the heater.



OXYGEN SENSOR (REAR)


The oxygen sensor (rear) is basically the same as the one mounted on the 4B1 engine.

CRANK ANGLE SENSOR


The crank angle sensor is basically the same as the one mounted on the 4B1 engine.

CAMSHAFT POSITION SENSOR


The camshaft position sensor is basically the same as the one mounted on the 4B1 engine.

DETONATION SENSOR


The detonation sensor is basically the same as the one mounted on the 4B1 engine.

BAROMETRIC PRESSURE SENSOR


The barometric pressure sensor is basically the same as the one mounted on the 4B1 engine.

OIL PRESSURE SWITCH


The oil pressure switch is basically the same as the one mounted on the 4B1 engine.
