2005 Liberty Renegade
Ongoing intermittent problem
Every so often my Jeep decides to drop into passing gear and not shift out. Stopping the car, turning off the engine and restarting clears the problem. With very few exceptions it is going uphill at altitude. I replaced the MAP sensor and putting in a clean air filter helps but it still happens and sometimes I can't go 3-4 miles after the reset without the problem coming up again.
This time I was smart enough to pull the code and apparently it is the heater on the oxygen sensor - bank 2 sensor 2.
What's going on?
