Number of O2 Sensors in a 2007 Dodge Caliber
The 2007 Dodge Caliber is equipped with two O2 sensors. These sensors are crucial for monitoring the oxygen levels in the exhaust gases to ensure proper engine performance and emissions control.

How much does it cost to replace all 4 O2 sensors?
The average cost for an Oxygen Sensor Replacement is between $362 and $412. Labor costs are estimated between $63 and $79 while parts are priced between $300 and $333. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
Which O2 sensor is sensor 2?
The Sensor 2 in question means that it is the sensor that is located behind your catalytic converter and the Bank 2 side of the engine is the side that does not contain the #1 cylinder.
What happens when both O2 sensors are bad?
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
How do I know how many O2 sensors I have?
How Many Oxygen Sensors Are There in My Car? Most cars will have several oxygen sensors. There will be one in front of the catalytic converter and one in every exhaust manifold. Modern vehicles usually have at least four oxygen sensors placed at key points in the exhaust system.
How do I know if it’s my catalytic converter or O2 sensor?
To check if it’s a clogged cat versus a bad oxygen sensor (when you don’t have a check engine light), grab a vacuum gauge. Connect the gauge to an intake manifold vacuum line. Start the engine, let it idle, and check the reading on the gauge. This is your baseline vacuum.
Should I replace all 4 02 sensors?
It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors.
How many O2 sensors are there?
Most cars have at least two oxygen sensors located throughout the exhaust system; at least one in front of the catalytic converter and one or more downstream from the catalytic converter. The “pre-cat sensor” regulates fuel supply, while the downstream sensor measures the efficiency of the catalytic converter.
What would cause all 4 O2 sensors to go bad?
Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.
How do I know which O2 sensor is bad?
What to look out for in a failing oxygen sensor:
- Check engine light: whilst the check engine light can come on for many reasons, it is normally down to an emission related issue.
- Poor fuel economy: a faulty oxygen sensor will upset the air to fuel mixture resulting in increased fuel usage.
What are the signs of a bad oxygen sensor?
Signs a Vehicle has a Bad O2 Sensor
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
