Q: Van lost power and limped home. 2016 Savana 2500

asked by on

My van lost power and was cutting out so it limped home. Later, it started briefly, but it ran very badly. I change the TDC sensor, coil, ignition module, distributor pickup, and the distributor is three weeks old. 12v is where it is supposed to be, but the 9+V on the TDC sensor where it should have 0, is 5V. I’m just about out of ideas as to what to try. What do you suggest that I do to fix my van?

As you may already know, trying to trace an electrical issue in when a vehicle goes into limp mode can be very frustrating and time consuming without having the use of a scanner. Nearly every vehicle when going into limp mode will have some kind of trouble code triggered, which will show up when having the computer scanned. I would recommend having this done in order to have a more precise plan as to what to repair. If you do not have access to this type of scanner I would recommend having an expert mechanic from YourMechanic come to your home to diagnose and repair the loss of power.
