Hi guys
I have a 2002 Jeep Cherokee Limited 3.7L Petrol (same as Limited in USA)
Now about a month ago, there were days on and off where a warning light was coming on then disappearing. Checked the obvious (oil levels etc), and checked the Jeep book which doesnt say a whole lot.
I took the car to Jeep whilst the problem was present, and the datalogger said the problem was "Throttle Position Sensor Low Voltage". Now they didn't test any further and said that it wasn't a wiring problem, and that the Sensor (TPS) needed to be replaced as it was not giving the correct signals. The car however drove perfect so at this point I did not change it.
Question 1) Do you believe the information provided above accurate considering no other tests were done? (Note I have tried unplugging it and replugging it and no contacts look dirty from what I can see)
Question 2) If it does require replacing, is it as simple as swapping it over plug and play? or does it require a professional to calibrate it or something?!
My second issue is that sometimes while driving the car will completely turn off. Then I have to try over and over again to turn it over and get it started again. Eventually it does.
Question 3) Could it be cutting out due to the first problem listed above? Perhaps it does not know where the throttle is and stalls?!
There has been no other indication of problems via dash lights etc in the last few weeks, and this cut out issue has been over the last couple of days.
