Have you noticed your rpms increasing (thereby increasing pump output/pressure) when you turn sharp left or right? You have a code, but have you noticed the Jeep acting different. Trying to find out if you've noticed the sensor doing it's job or not, is it working?
The easiest thing to do would be to get another sensor and see if that fixes it. Although you could be doing so unnecessarily if your current sensor is not the problem.
You might want to start with the circuit and check that you have the proper voltage and good ground at the sensor plug to rule out an electrical problem before the sensor.
