Customer Question
Getting the p0128 code...

Getting the p0128 code and the jeep wont start also having the red lighting bolt on the dash. was coming home last night stopped and got gas and when I went to leave it wouldn't start

Mechanic's Assistant: Have you checked the fuses? The dashboard bulbs?

All fuses looked good

Mechanic's Assistant: What is the model/year of your Jeep?

2012 the check engine light came on about a week prior to it happening

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Yes doing the work myself. changed battery cuz it was under warranty and I also changed the coolant temp sensor closest to the dash that relays the info

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Was making a slight jerking when driving periododically when driving. seemed to be fuel throttle position

Hi that code you mean multiple things from a bad coolant temp sensor, stuck thermostat or a bad intake temperature sensor. Do you have a scan tool that will show live data for the sensors ?

Jeep Mechanic: anthony proulx, ASE Certified Technician replied 2 months ago
Ok unless you just put in the intake temp sensor, and the thermostat you would need to use the scan tool
