Where are the sensors on a Jeep Laredo?
I have a 2005 cherokee laredo and after first replacing the TCM, my jeep is still having the same problem — speed go limp or stop pulling while driving, we are now trying to change the input/output sensors and can’t find the spot on transmission where we have been told they go.
How does the N2 sensor work in a jeep?
With the vehicle moving forward or reverse, N2 speed sensor reading will be greater than zero in all gears. Whenever the K1 clutch is applied (2nd, 3rd, and 4th) N2 will be equal to N3. There is no speed sensor internal to the transmission that directly measures input shaft speed.
Where are the input and output sensors located?
The engine speed is fed to the TCM via can bus thus providing impeller speed. There is no speed sensor internal to the transmission that directly measures output shaft speed. ABS wheel sensors provide output shaft speed. K1 clutch (N3 speed sensor) will show no rotation whenever the B1 Brake is applied.
Is there a speed sensor on the transmission?
There is no speed sensor internal to the transmission that directly measures input shaft speed. However, when K1 is applied N2 equals input shaft/turbine speed. The engine speed is fed to the TCM via the vehicle’s communication bus thus providing impeller speed.

Why is the speed sensor on my Jeep going bad?
When I first noticed this issue I saw that for the first time the RPM went to approx 3200 RPM. When I told my friend who works on cars he said that the Jeeps speed sensor tells the computer when to switch the gear based on speed that the vehicle is traveling and that if the sensor was going bad that could be the cause of my issue.
Can a bad speed sensor affect shift timing?
Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…
Why is my speedometer not working on my Jeep?
The ECU is programmed with your Grand Cherokee’s gear ratios and stock tire height. It combines this data to send the speed reading to the instrument cluster. The causes of a bad speedometer will typically be found in these four things:
Why is the O2 sensor on my Jeep Cherokee bad?
Your Cherokee’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly.
Why does the Check Engine light come on on my Jeep Cherokee?
Oxygen sensors can change the way that your 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.
Are there any problems with the Jeep Cherokee?
Stock XJ Cherokee Tech. All XJ Non-modified/stock questions go here – Great info threads in here… – Scan Code Problem Description P0030 (M) 1/1 O2 Sensor Heater Relay Circuit Problem detected in oxygen sensor heater relay circuit.
What happens when the O2 sensor goes bad on a Jeep Grand Cherokee?
When an O2 (oxygen) sensor go bad, it’ll cause your Jeep Grand Cherokee ‘s engine to run less efficiently. 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.
