Look on either the exhaust manifold or exhaust pipe.
under he motor mount
It is possible as the signal from the oxygen sensor is sent to the computer
you gotta take the old one out first
I have a 99 Metro 1.3L. This car has two oxygen sensors, one in the exhaust manifold and the other is after the Catalytic Converter. Hope that helps.
They are blue, black and white. They can be found extending from the catalytic converter (the upstream O2 sensor) and possibly from a second source (the downstream sensor).
It has 1 O2 sensor located on the exhaust manifold befor the catalytic converter
to change o2 sensor ,you need to buy a o2 sensor socket from a parts store then disconnect neg terminal on battery ,after that disconnect wire connecter on o2 sensor and remome o2 sensor
in the exhaust pipe right under the manifold it is easy to get to right in front under the hood
To change the camshaft position sensor on a 2001 Chevrolet Metro, first disconnect the negative battery terminal to ensure safety. Locate the sensor, which is typically near the camshaft or engine block, and unplug the electrical connector. Remove the mounting bolt and gently pull the sensor out. Install the new sensor by reversing the process—insert it, secure it with the bolt, reconnect the electrical connector, and finally reconnect the battery.
I have a 1998 Metro with the 1.3l and the Camshaft Position Sensor is located on the bottom of the oil pan.
The MAP (Manifold Absolute Pressure) sensor on a 1997 Geo Metro is typically located on the intake manifold, near the throttle body. It is a small, rectangular component with an electrical connector and a vacuum line attached to it. To access it, you may need to remove some engine covers or components for better visibility. Always ensure the engine is off and cool before attempting to locate or service the MAP sensor.
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
