2001 2.5L automatic. I recently purchased a data logging scan tool and took my truck for a 20-minute joy ride. It's been running rough and getting about 175 miles from a tank of fuel. When I got back from the trip, I got the dreaded P1401 code and another response," vehicle operational temperature not reached". I checked over the EGR system. Everything looks fine. All the hoses are there and the EGR valve is holding vacuum. The sensor may be faulty. I'm not sure if that can be checked or just toss a new one on. What do you use to clean the EGR valve? The engine temp recorded by the scan tool shows a high temp of 190.0 with an average temp of 174.5. A few years ago, I replaced the timing belt and while I was there, I replaced the water pump and T-stat, a 195F unit. The system is full as well as the overflow tank having a little coolant in it. I also have excellent heat. Could the problem be a faulty engine temp sensor?
