I have a cam sensor on my bus starting to get bad. The last couple mornings I have started it and the check engine light comes on for 10 seconds or so then it goes out, then it sometimes sputters when I come to a stop. Its a 2004 Blue Bird International with the DT466 engine in it. I was told that the DT466E will run with every other sensor bad except the cam sensor and the oil pressure sensor. One very experienced mechanic I talked to said that the cam sensor for a t444e will work in a dt466 and their much cheaper as well. I was told the t444e sensor has the exact same dimensions the only difference is that it will advance the timing 2-3 degrees, I was wondering if anyone on here had ever tried the swap. The dt466 sensor is $129.00 the t444e sensor is only $17.00 the they both look exactly the same.
I would personely go with OEM. I have run lots of 466's and 444e's. I have very seldom changed the cam sensor twice on the same engine. How many miles does your engine have on it now.That probably will be about the same mileage you should get out of a new one. Unless you have some kind of problem that is causeing them to fail.
I have used 444 sensors in 466's many times...some fore 75000miles and never had any trouble. A 466 sensor will not work in a 444 because its turned a little in the holder and wont bolt in without grinding the hold down tab.
