How does the O2 sensor work in a Pontiac Sunfire?
The oxygen (O2) sensors in a Pontiac Sunfire measure the amount of oxygen in the exhaust gas and relay this information to the powertrain control module (PCM). The PCM uses this information to adjust the air-to-fuel ratio and the ignition timing. There are two O2 sensors in a Pontiac Sunfire: one primary sensor and one secondary sensor.
Where are the O2 sensors located on a car?
The sensor number is telling us where on the exhaust system the O2 sensor or Exhaust temperature sensor is mounted. The 1st sensor is located closest to the engine and the last is located at the rear of the exhaust system. Generally, if we are talking about O2 sensors:
Where is the secondary sensor on a SunFire?
The primary sensor is in the exhaust manifold and the secondary sensor is underneath the car, in the exhaust pipe after the catalytic converter. Turn the ignition to the “OFF” position and shift the Sunfire’s transmission into “Park” or first gear (manual). Set the parking brake and open the hood.
Where are the sensor 1 and 2 located?
What is Sensor 1 & 2? The sensor number tells us where on the exhaust system, the O2 sensor or the Exhaust temperature sensor is installed. The 1st sensor is located closest to the engine, and the last is located towards the rear of the exhaust system.

Where is the secondary oxygen sensor located on a car?
The secondary oxygen sensor is located six inches downstream from the catalytic converter. It has a single wire connector and screws into the exhaust pipe. Kyle Sanstrom has been writing professionally since 2008.

Why is my O2 sensor not working on my Toyota 4Runner?
One of the vehicles it didn’t work with was a 1997 Toyota 4Runner with the V6 engine. In this case there was voltage on both wires to the O 2 sensor heater circuit. Most computer systems will also monitor the current flow to the sensor. The light’s current draw was not within the operating range of this system’s heater circuit.
What is the repair manual for a Pontiac Sunfire?

Where is the secondary oxygen sensor on a Honda Accord?
Locate the catalytic converter. It is underneath the vehicle, oblong and in the center of the exhaust pipe. The secondary oxygen sensor is located six inches downstream from the catalytic converter. It has a single wire connector and screws into the exhaust pipe.
Where is the primary oxygen sensor on a car?
The primary oxygen sensor is located on the bottom of the exhaust manifold, and has a single wire connector attached to it. Locate the catalytic converter. It is underneath the vehicle, oblong and in the center of the exhaust pipe.

Where is the oxygen sensor on a Grand Am?
The upstream sensor will be located along the front exhaust pipe before the catalytic converter. The downstream sensor is found right after the catalytic converter on the back exhaust pipe. The sensor’s body is cylindrical in shape, about the size of a spark plug, and has a pigtail electrical wire.
Where is the oxygen sensor located on a car?
This information is used by the Powertrain Control Module (PCM) to determine the correct air to fuel ratio for your engine in real time. The sensor is located in the exhaust system and allows the fuel injection and engine timing to work efficiently, which assists with emissions control.
Where is the O2 sensor in the engine?
The engine computer is responsible for calculating how much fuel the engine needs based on the amount of oxygen in the system, and it relies on a good O2 sensor to function properly. The sensor is mounted in the exhaust manifold to monitor the amount of oxygen in the exhaust.
Where are the upstream and downstream oxygen sensors?
1 Upstream oxygen sensors are located in between the engine and the catalytic converter 2 Downstream oxygen sensors are located in the catalytic converter or farther away from the engine than the catalytic converter 3 Locate your vehicle’s firing order diagram 4 The bank that contains cylinder one is bank one
