Number of O2 Sensors in a Dodge Challenger
The Dodge Challenger typically has four O2 sensors. These sensors are located both upstream and downstream in the exhaust system. The upstream sensors are located before the catalytic converters, while the downstream sensors are located after the catalytic converters. The purpose of these sensors is to monitor the level of oxygen in the exhaust gases, which helps the engine’s computer to adjust the air-fuel mixture for optimal performance and emissions control.

How do I know if my O2 sensor is bad?
Light you might also experience hard starts a rough idle misfires or sluggish acceleration. If your vehicle is 1996 or newer it’s recommended you change your oxygen sensors.
How many O2 sensors do I have?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
Should I replace all 4 O2 sensors at once?
Do I need to replace all of the sensors at once? 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.
How many O2 sensors does a V8 have?
three oxygen sensors
Traditional V6 and V8 engine vehicles typically have three oxygen sensors: a left bank and right bank upstream sensor as well as a downstream O2 sensor. 4 cylinder transverse engines usually have two O2 sensors: one upstream and one downstream.
How many O2 sensors does a Dodge Charger have?
Get it properly diagnosed. All 4 O2 sensors going bad seems highly unlikely.
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.
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.
Should I replace both O2 sensors?
In this case, it is best to replace both corresponding sensors on each bank if you have a V6 or V8. For instance, if your bank 1 upstream sensor has gone bad, you should probably also replace your bank 2 upstream sensor. If you don’t, then it is likely that the bank 2 upstream sensor is going to go bad soon.
What are the 3 common causes of O2 sensor failure?
Below are the top reasons that cause the oxygen sensor to fail:
- Long Time Usage. The oxygen sensor as with all electrochemical sensors, loses sensitivity after long periods of use.
- Contamination.
- High Temperature.
- Irregular Maintenance.
- Using Low-Quality Gasoline.
Will an O2 sensor work without a catalytic converter?
an O2 sensor does not need a cat to function properly. There are aftermarket fuel injection systems that use an O2sensors to keep fuel mixture anywhere you want, usually way richer then is safe with a cat. The sensor just reports free oxygen, the software it reports to does whatever it’s written to do.
