Seventeen - Forty

We met our friends the Sheltons for dinner yesterday, and on the way home I got a check engine light on the truck.

There is a diagnostic trick on  a Dodge – without starting the engine, turn the key on and off three times and then leave it on – that will display the OBD-II code(s).  I did that when we got home and the code displayed was P1740.

That code indicates that engine rpm did not drop fast enough to satisfy the on-board computer when shifting to a higher gear.  It could be something as simple as a poor connection, or as complicated and expensive as a bad torque converter. 

It is a fairly common code, and often shows up after a transmission has been serviced.  Ours was, but it was several thousand miles ago.

The consensus on the Dodge Truck forums is that if everything else seems normal, you should just reset it and see if it comes back.

I’m going to try that, but with the way my luck has been running lately……
