P0796 code definition

The presence of the P0796 code in the PCM means that an abnormal reading from the electronic pressure control solenoid, or the related circuit, was detected.

What the P0796 code means

The electronic pressure control solenoid is one of the many components used to facilitate and monitor gear shift changes in the transmission. In particular, this part provides the data that allows the PCM to regulate the transmission fluid pressure. If the transmission pressure doesn’t align with the manufacturer’s specifications, it is likely that the gear shift operation will not be performing correctly. In this case, the PCM will store the P0796 code.

What causes the P0796 code?

A faulty electronic pressure control solenoid is the most likely cause of this code; however, blocked transmission fluid passages, low or dirty transmission fluid, faulty electrical components within the circuit, or internal transmission failures could all be to blame.

What are the symptoms of the P0796 code?

Symptoms of the P0796 code can vary, but may include:

  • Disabled shifting function
  • Torque converter clutch may fail to engage or disengage
  • Harsh shifting
  • Slipping transmission
  • Overheated transmission
  • Decreased fuel economy
  • Illuminated Check Engine lamp

How does a mechanic diagnose the P0796 code?

After an OBD-II scanner detects the P0796 code, a technician should begin with an inspection of the transmission fluid. If it is low, it should be refilled; if the fluid is dirty, or smells like it is burnt, this could mean that the entire system needs to be flushed, and refilled with clean fluid.

The next step is to check all electrical components, repairing or replacing any wiring or connectors as necessary. The technician should then continue diagnosing the pressure control components until the fault is discovered. At each step, the mechanic should be sure to clear the code from the PCM and retest the system; if the code does not reappear, it’s likely that the issue has been resolved, and no further repairs will be necessary.

Common mistakes when diagnosing the P0796 code

The most common misdiagnosis with the P0796 code is replacement of the high pressure pump, when the solenoid or the electrical wiring are actually to blame.

How serious is the P0796 code?

Because this code relates directly to the operation of the shifting function, it is very important that it be repaired as soon as possible. If the issue behind the P0796 code is not addressed immediately, it can cause major issues down the road.

What repairs can fix the P0796 code?

There are many ways that a technician can address a P0796 code detection. They include:

  • Replace a faulty electronic pressure control solenoid.
  • Clear blocked transmission fluid passages.
  • Refill low or dirty transmission fluid.
  • Repair or replace faulty electrical components within the circuit.
  • Correct any internal transmission failures.
