What Does The Dodge P1794 Code Mean?

The input, transfer and output speed sensors use a common ground circuit. The loss of this common ground results in the input signal being sensed for both. After a reset in neutral, and after observing a specific ratio, the Speed Check Fault Counter will increment. Because the speed sensors and thermistor share the same ground circuit, this DTC may indicate a loss of the common speed sensor ground. In some cases this fault will cause a Gear Ratio Error DTC to be set.

What Are The Potential Causes Of The Dodge P1794 Code?

  • Speed sensor ground circuit open
  • Powertrain control module (PCM)
