does anyone what this error code means P0132 - HO2S Circuit High Voltage Bank 1 Sensor 1?

Since you don't say which car, we can only guess. My guess is that your upstream O2 sensor is bad. This assumes that you have a car that is an '96 or newer and two O2 sensors.

it is a 99 jeep grand cherokee....

I have a '94 and a '98 but this is what I found for online for the WJ codes.

"Oxygen sensor input voltage maintained above normal operating range."

I hope this helps.
