How many oxygen sensors does a 2003 Dodge Ram have?

How many oxygen sensors does a 2003 Dodge Ram have?

You have 4 sensors. 2 are upstream sensors and 2 are downstream sensors.

What kind of oxygen sensor does Dodge Ram use?

Sounds like your oxygen sensors have failed, and here is how to replace them. This article applies to the Dodge Ram 2nd Generation (1994-2001). Your Dodge Ram uses two types of O2 sensors: a primary and secondary.

How many oxygen sensors does a car have?

All post-1996 vehicles have a lot of emissions equipment, including oxygen sensors. Most emission-controlled cars have two to four oxygen sensors, depending on the amount of cylinders and exhaust pattern. These sensors are broken down into two categories, upstream and downstream.

Where is the downstream oxygen sensor located on a car?

Downstream. The downstream oxygen sensor is located directly after the catalytic converter. This sensor measures the pollutants making it through the converter and out of the tailpipe. The data from this sensor is compared to that of the upstream sensor. If the data between the two sensors becomes more similar, the vehicle’s computer may trigger…

Where is the O2 sensor in the exhaust manifold?

Fig. 2: Location No. 1 — Typical O2 Sensor located in the exhaust manifold Fig. 4: Location No. 3 — Exhaust collector (where more than 1 pipe joins together)

How many oxygen sensors does a Dodge Ram have?

So, do I have two, three, or four Oxygen sensors? 2005 Dodge Ram 1500 SLT 4WD Quad Cab 5.7 Hemi gasoline. In previous years I have changed two – one upstream (“before” the catalytic converter) and one “down”. i THOUGHT that were all.

Can a bad oxygen sensor cause a check engine light to come on?

The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong). It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your Ram:

Where are the O2 sensors on a Volkswagen Golf?

Sensor 1- Sensor 1 would be the first O2 sensor in the line of sensors starting with the exhaust manifold and making its way back to the exhaust pipe. An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”.
