TROUBLE CODE P2106

There is no power when accelerating from a stop. The engine is reving high yet barely moves. Once it reaches third gear it runs normally, but it is struggling to get there. The overdrive light is blinking and check engine light just came on. Got two codes P0720 and P21061. P0720 was for the speed sensor which we replaced, but P2106 has not been fixed and no there are no improvements on the vehicles performance. If anyone has any advice please inform me. I don't know what to do next besides take it to the dealer, which I am trying to avoid.

P0720 is the output shaft speed sensor for the transmission. If the sensor isn't faulty you need to check the wiring for opens and shorts. If that checks out than I think your transmission is not good. the p2106 is a limp mode code. Correct me if I am wrong anyone. this post is six years old so I am sure they found the answer and I would like to know if I am correct.

SOURCE: hard shift and blinking overdrive

The blinking overdrive button is telling u that a serious fault has occurred in the electronic controls or a mechanical fault such as excess slippage is occurring.

SOURCE: Trouble code P2135, and P2106.

I have the same problem on my 06 explorer.
Ford Dealership told me i needed my "electronic throttle body assembly" replaced.
It would cost about $630.

I'm a little hesitant to let them do that service though, because it may not be the whole thing that needs replacing. I'd just look in to getting the Throttle Positioning Sensor replaced.. which would cost a lot less.

2006 Ford F-150 5.4 engine: code P0191 fuel rail pressure sensor circuit range / performance

First step is to change the fuel filter and test the car. If the problem still occurs: The fuel pump driver module was corroded through from salt and was malfunctioning. Bought a new one and runs great. Problem fixed. See pictures below:

This is why salt destroys cars.

1997 Chevy Camaro V6 I have posted about this once already today but I want to give more information and hopefully a more accurate response. The vehicle is under reving while idling in drive or any other...

A flashing check engine light indicates active engine misfire. There should be codes set for these conditions. It could be low fuel pressure, but if you have not replaced the spark plugs and wires, I would look there. Failed ignition coils or ignition module can be culprits. Also plugged exhaust (catalytic converters) could be to blame as well. To test the catalytic converters, remove the oxygen sensors between the engine and converters and go for a drive. You can also unbolt the converters and run open exhaust. It will be loud, but if performance improves and normalizes, your exhaust is plugged and you will need to replace the converters.

Fault code P2106

is it the ecotec engine fitted 1.8 or 2.0./2.2l or the diesel 1.7 engine.. how long have you not used the air con for. not using it for a long time you can damage the pump the flown sensor. even the temperature sensor. but if the engine is trying to stall with the ac on then the pump may have a fault. ac should be run for 10min once a week no matter the weather. stops you having problems later.

Stumbling on acceleration

You may be cruising down the wrong road with the exhaust idea but then you might be right. An exhaust restriction should also cause the engine to run hot. A faulty cat should also set some codes.
If the injectors are dirty, you may have a very lean fuel mix on one or more cylinders under acceleration, which would go away once you are not under load. And injector problems won't set any codes unless an injector stops working completely. Low fuel pressure could cause the same type of issue.

Problems accelerating

the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

Normal for a Boxster shifter to move a little on acceleration?

I have had vehicles do that, the amount of torch the engine is putting against the transmission makes the engine and tranny tilt to one side. This is normal. If you watch a truck (pick up) or a car at stop, idle high (reving up and down) you will see the front of the car slightly rock from side to side. This is the torque that the engine is pushing against the tranny; since the engine and tranny are bolted to the frame, the engine and tranny can only move so far; therefore the whole car/truck will move - and yes, as well as the tranny shifter. You can take it in and have the tranny mounts checked to be sure, but I'm sure it's fine.
