How is the transmission of a Ford Expedition controlled?

Electronic transmissions are controlled by a computer, otherwise known as the powertrain control module (PCM). Troubleshooting the PCM is a complex job that requires some special test equipment that the average do-it-yourselfer does not have—nor is cost effective for them to purchase.

How does the speedometer work on a Ford Expedition?

The programmable speedometer/odometer module (PSOM) receives input from the rear brake anti-lock sensor. After processing the signal, the PSOM relays it to the PCM and the speed control module.

What causes a Ford Expedition to stall at a stop?

Bad Solenoid. When your Ford Expedition stalls at a stop, just as it would if it had a manual transmission and you neglected to push in the clutch, that’s a sign that one of the solenoids is malfunctioning or has gone out.

How does the ignition control module work on a Ford Expedition?

The ignition control module operates by sending crankshaft position information from the crankshaft position sensor to the ignition control module. The ignition control module generates a profile ignition pickup (PIP) signal (engine rpm) and sends it to the PCM.

Why is my Ford Expedition taking a nose dive?

The faster the car is moving coming into that stop, the more the “nose” of the car will dive down and the rear will pop up. If you’re experiencing a nose dive in your Ford Expedition you are putting a lot of strain on what’s left of your air suspension. Avoiding the problem will only make it worse.

What is the MAF sensor on a Ford Expedition used for?

What happens if there is no reverse shift?

Splitting the circuits electrically is a very basic step in the “No Reverse” shift concern diagnosis. Electrically controlled transmissions generally have a built-in safety program that prevents the transmission parts from breaking based on a rolling speed shift reference during the reverse engagement.

Can you use a non Pats key on a Ford Expedition?

If you use a non PATS key, such as one that was cut simply to open the doors from an all-metal key blank, the system will remain armed.

How does the transmission work in a Ford Expedition?

The Powertrain Control Module (PCM) and its input/output network control the following transmission operations: Torque converter clutch operation. The transmission control is separate from the engine control strategy in the powertrain control module, although some of the input signals are shared.

Why does my expedition not accelerate when the RPMs go up?

If your Expedition won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue. Somehow, the power that your engine is creating is not making it to the rear wheels. This is typically a transmission related issue. Here are the most common cause of acceleration with the RPM’s going up:

How does a variable force solenoid work in a transmission?

The variable-force type solenoid is an electro-hydraulic actuator combining a solenoid and a regulating valve. It supplies electronic pressure control that regulates transmission line pressure and line modulator pressure. This is done by producing resisting forces to the main regulator and the line modulator circuits.
