Here in the last month bout once a week I go to crank my 05 with 108k miles and it will say engine failsafe mode. I turn the key off and turn it back on and it's fine. It only threw one code which was a overev code which I haven't done. Does anybody know what's going on? It seems to be getting more frequent.

 

happened to my dads, have dealer check throttle position linkage sensor or something along the lines of that, took dealer 4 months to figure it out on dads truck, and happened 10 plus times! good luck man!

 

P2106 was my code I believe. I needed a new TBS.

 

When it goes into failsafe mode, pull the codes right away!

 

It only threw that one code. I'm thinking it has something to do with the throttle sensor or something.

 

If that is it how much is a tps?

 

I thee the same code p2106, happened 3x. Cleared it with my edge but it kept coming back. After hours of searching, I read the issue is the Throttle Position Sensor and you have to get a reflash at the dealer for the new file. There's a TSB on it. I found the sensor on Amazon for around $60

 

ok got 2 codes one is P2110 and P2107 both are throttle actuator control system.Any suggestions? Also its getting worse

 

Look above on my previous post. Did you read it? There's your answer

 

Replace your throttle body and have your PCM reflashed.
