Where are the O2 sensors located on a 2004 Jeep Grand?
Re: Where are the o2 sensors located on a 2004 jeep grand… Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines… An O2 sensor is a galvanic battery that provides the PCM with a voltage signal (0-1 volt) inversely proportional to the amount of oxygen in the exhaust.
Can a bad oxygen sensor cause a Jeep Grand Cherokee to go bad?
Your Grand Cherokee can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on. The good news is, if you end up discovering that the oxygen sensor is bad, they really aren’t that expensive to replace.
Where is the oxygen sensor in the engine?
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”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
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 Grand Cherokee:

Why does the Check Engine light come on on my Jeep Grand Cherokee?
Oxygen sensors can change the way that your Grand Cherokee’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
