How does a mechanic diagnose the P0726 code?įirst, the mechanic should read the codes stored in the computer using an OBD II scanner. Dirty, contaminated or low transmission fluidĪ range of different symptoms could be present with the P0726 code.A loose connection to one of the sensors.A short or open in the wiring harness to one of the sensors.A failed transmission output speed sensor.There are multiple potential causes for the P0726 code. The computer expects the engine speed to increase gradually, and if that does not happen, whether actual or due to a faulty signal, the P0726 code will be stored. The upshot is that the transmission cannot provide a shifting strategy because the computer is unable to determine the actual speed of the engine.

This signal might be erratic, outright incorrect, or irrational. Essentially, the car’s computer is receiving an incorrect signal from the engine speed input circuit. The P0726 code is related to other similar codes dealing with the crankshaft position sensor and engine speed input circuit. Because of this, the transmission will not be able to shift correctly. The P0726 code means that the car’s computer has received an incorrect, irrational or erratic engine speed signal from the engine speed input circuit.
