How many O2 sensors does a 1997 Dodge Ram 1500 have?
There are only two sensors on it. One right where both pipes come into the cat, and one about a foot behind the cat. This is the only two that there are. They are both different.
Where is the O2 sensor on a Dodge Ram 1500?
The o2 sensor in a Dodge Ram 1500 is located after the headers on the exhaust pipes.
Is there 2 oxygen sensors?
Two oxygen sensors per exhaust pipe allow a vehicle’s engine control computer to compare the cleanliness of the exhaust before it enters the catalytic converter to the exhaust after it exits.
What are the 4 oxygen sensors?
V6 and V8 transverse have four oxygen sensors including a left or front bank upstream; right or rear bank upstream; rear of the engine; and a downstream sensor. 4 and 6 cylinders in-line have three oxygen sensors including a front and rear bank upstream and a downstream sensor.
How do you bypass an O2 sensor?
How to Bypass Oxygen Sensors
- Raise your vehicle onto jack stands.
- Place jack stands underneath the front pinch welds located underneath the front doors (underneath the vehicle) and lower the vehicle onto the stands.
- Remove the electrical plug from the O2 sensors underneath the vehicle.
What should an O2 sensor read at idle?
A good O2 sensor should produce an oscillating waveform at idle that makes voltage transitions from near minimum (0.1 v) to near maximum (0.9v). Creating a lean mixture by opening a vacuum line should cause the sensor’s output to drop to its minimum (0.1v) value.
What should Stft be at idle?
Ideally, the STFT and LTFT should be within a few percentage points of zero when the engine is idling or being held at a steady RPM. Good LTFT values should be as close to zero as possible, though they can range from 5 to 8 percent depending on the condition of the engine.
What should fuel trims be at idle?
Note though that since sudden changes in the engine speed can cause short-term fuel trim values to fluctuate wildly, all fuel trim values should be taken at a minimum of at least three steady engine speeds, these being at idle, at about 2500 RPM, and at about 3500 RPM.
Why does my O2 sensor read 0 volts Silverado?
Either the O2 sensor is bad or you’re running too lean. The fact that fuel trims haven’t updated just means the ECU hasn’t gone into closed loop yet…which makes sense given the lack of an O2 reading. Try richening your injector compensation and see if you can get the O2 sensor to move.
What should the voltage be on a 02 sensor?
An O2 sensor will cycle between 0.10 to 0.90 or almost 1 volt. An O2 sensor has to reach the 0.8x Volts amplitude mark while at full operation. An O2 sensor also has to reach the 0.1x Volts amplitude mark while at full operation.
