Question about Ford Expedition
Hello, I enjoy a challenge. I have several things for you to check and start with.
The Ignition switch can have 2 adjustments, one at the top on the Ignition switch housing and the second on the bottom of the steering column at an Interlock switch. The plastic column cover will need to be worked out of the steering wheel tilt mechanism to get at the Ignition switch. Disconnect the Battery NEG post and put your key in the lock cylinder in either the ACC or Run position while pushing on a spring button at the bottom of the lock. You can use a drillbit to press this part and pull up with the key to remove the Lock cylinder. Replace with a new Ignition switch.
Before replacing the column cover, take time to Temporarily reconnect the Battery and align the Ignition switch and the bottom Interlock switch so you are sure all positions on the Ignition key work. Disconnect the Battery again and fit the plastic cover back on. Then reconnect the Battery.
By replacing the Ignition switch, you should have eliminated the Starting problem and a Battery drain problem which could make the Antitheft kick-in. These Models have Antitheft systems which will sense a low Battery level. You need to have a Draw test done on the Battery to eliminate a failing Battery as the cause of the Antitheft Code.
Your Shifter also has an Interlock. It is suppose to let the Starter work in Park, and it is suppose to keep you from shifting the trans without your foot on the Brake. If there is binding or misdirection you could need the TRANS sensor Aamco recommended. This would explain much of the Revving and not going into gear problems. You may need to have this separate Interlock adjusted.
You can also get free testing done at Autozone, Oreillys, and Advance autoparts instead of the expensive Dealers. But they are not going to install anything you need.
Limp mode is when the Timing of the engine, vehicle speed, and shifting is limited . You should not be able to go fast or race the engine in this mode. Something else was happening to make the engine race.
I hope you find my Solution very helpful and I have tried to suggest needed inexpensive parts to remedy this problem. The lighting of the shifter can be a simple burned out bulb.
