P1494 Dodge ram van

Question

1998 dodge ram 3.7l code showing is p1494

Answer 1

HI there,

This code is for the leak detection pump switch or mechanical fault.

Specifically when the computer is calling for the LDP to test the system it's not performing. This could be a wiring issue or the pump itself. The LDP will have to be tested to determine the cause of the problem.
