Coding a 2106 and a 2135 on 2006 Ford Expedition. Replaced the Throttle monitor sensor and cleaned the throttle body. Drove car and it ran good but next time it did the same thing. Engine failsafe and engine light back on and coding same codes

throttle actuator sensor ???? TPS - throttle position sensor - throttle body ?? Was there a code ? if so what was it ? Your vehicle has electronic throttle control . Sensors in the gas pedal assembly ,two sensors in the throttle body . Computer controlled .

Vacuum leak , mass air flow sensor dirty , dirty throttle plate . YouTube videos will show you how to diagnose this problem . How to Clean an Electronic Throttle Body Safely How To Clean Mass Air Flow Sensor Properly Misfire caused by vacuum leak

Good luck an good hunting ! an have fun !!!!

replace the throttle body. you can be dissatisfied, but its going to happen to any make or model. vehicles are made to break. if they werent then there would be no need to buy new cars

Your TPS-throttle positioner sensor needs to be replaced I think.

Computer does that

Clean throttle plate-CRC Throttle Body Cleaner
Clean MAF Sensor-CRC MAF Cleaner
Install new spark plugs--70,000 miles- Champion 7989 one piece plug
New O2 Sensors-100,000 miles,front 2
only,closest to engine

Disconnect the accelerator cable from the throttle body as well as the electrical connectors for the throttle position sensor and the idle speed control solenoid then disconnect the plastic air intake duct, remove the four bolts securing the throttle body assembly to the intake manifold and remove it.
Clean it out using an old toothbrush and a can of throttlebody and air intake cleaner , then reinstall it by reversing the steps above.

ETC Failsafe?

It's your responsibility to keep it maintained . Not just to jiffy lube !To the Dealer to have diagnostic's run on the electronics. Accelerator Pedal Position Sensor vs. Throttle Position Sensor

Try cleaning the throttle body with throttle body cleaner. Remove intake hose at throttle end. Spray cleaner on butterfly and open throttle by hand, spray inside throttle body and let the build up run back out. Wipe clean with clean dry cloth, and repeat. It will be hard to start after putting back on, but it will start with 5-6 engine turns. It's the cleaner in the throttle. The injectors ca be cleaned with them in, they will run clean the fuel system. I usually buy Lucas injector cleaner and add 109 octane booster from wal-mart or your local parts store. Lucas is wonderful and the booster will clean your system. A lot cheaper than a shop cleaning it.

Not knowing what engine etc, a good place to start would be to give the inside of the throttle body a good cleaning especially around front plate area with throttle body spray cleaner, as well as listen and look for possible crack or break in any vacuum lines, or loose nuts/bolts at throttle body and area.
