This is an interesting one. Recently had a camshaft replaced on the Jeep. Outdoor Temperatures dropped and a P1281 code was triggered. Odd because 2 years ago I put in a new 195-degree Carquest Premium Thermostat.
Anyway, check out what I saw when I took off the housing. Some sort of plastic piece and they used a ton of glue! Has anyone ever seen this before and could that be what caused the thermostat to stick open? The shop had to put a new gasket on the thermostat when they worked on the camshaft.
The video below shows me removing the plastic.
On a side note, if you ever have temperatures below 185 while running idle/parked or 175 while driving, it's probably a stuck open thermostat!
