About the Cherokee
The Cherokee, one of the most iconic of the Jeep offerings, first made its debut in 1974. Since its release, there have been a total of five generations to hit the markets.
The previous two generations of the model were sold as the Jeep Liberty for the North American market.
It represents the smaller sibling of the larger, more luxurious Jeep Grand Cherokee.
Sitting in the compact crossover SUV class puts the Cherokee up against the Ford Escape, Honda CR-V, Toyota RAV4, and many others in the very competitive class
One of the most common issues that the model has suffered from is P0123. This code indicates a high voltage input for the throttle/pedal position sensor.
A sensor code like this likely means that the throttle position sensor needs to be replaced. Owners have reported that this is a common fix for this issue. It is a good idea to check the sensor circuit for electrical issues.
The Cherokee is also prone to suffering from P1281. This manufacturer-specific code indicates that the engine is not coming up to operating temperature properly.
Owners have reported that simply replacing a defective thermostat is the most common solution to this issue.
Another manufacturer-specific fault code that the Cherokee is susceptible to fairly often is P1391. This code indicates that there is a loss of signal from the crankshaft position sensor or the camshaft position sensor.
Of course, the first step with a code like this is to check both the crankshaft position sensor and the camshaft position sensor. It can also be helpful if there are additional fault codes that relate to either of these sensors.
