P2135 TPS Sensor Voltage Correlation DTC
Symptoms of a P2135 code can range from stalling when you come to a stop, total lack of power, no acceleration, sudden loss of power at cruise speeds or stuck throttle at current rpm. Additionally, the check engine light will illuminate and the code will be set.
It's been my experience that the wiring connector or "pig tail" on the throttle body gives problems in the form of a poor connection.The female terminals on the pigtail corrode or pull out of the connector. Possible bare wire on pigtail shorting to ground. The top cover on the throttle body distorted preventing the gears from turning properly. The electronic throttle body is faulty. The accelerator pedal sensor or its wiring failed. The engine management computer has failed. The TPS sensors were not correlating for a few seconds and the computer needs to be cycled through its relearn phase to restore active response to the throttle body, or the computer needs reprogramming at the dealer.

You may want to check with the dealer or do some internet research on the code - - the generic code means there is a problem with the throttle position switch circuit. It could be different for a Mercury product.

The keyless entry module is located in the rear of the vehicle on the driver's side. You will need to partially remove the left rear panel in the cargo area. You will then see the keyless entry module bolted behind a metal reinforcement bar. There is a sticker on the module that has the 5 digit entry code.

spray a small amount of W/D 4o into the key lock and then put the key in and move it back and forward until the lock free up and also spray a small amount in the inside lock of the door as well and then do the same on the other side the reason you had this problem is because the last owner only used the remotes to lock and unlock the doors and not the key sometimes.

Before you do this you might want to try fresh gear lube. On Ford products they use a synthetic additive in the rear and not in the front 4x4 axle.
The next thing would be to determine if it is a wheel bearing or a pinion bearing. You have to pull the axles and eliminate them as the problem. You might get lucky and not need to do the pinion.
The technical part of shimming the pinion gears with replacing the pinion bearing is about the worst part of the job. You won't know about the gears until you see them. You will need extra shims on hand.
It is a moderate job for two people. If you have all the parts it can be done in a day.

Oxygen sensor or 0 2 sensor is : po174- Heated oxygen sensor switching slow right side po171-Heatd oxygen sensor unable to switch right side. C hange out 02 sensor once you do that if engine light doest turn off you may need to take it and have it reset.

it means the catalyst is worn out, the efficiency is monitored by sensors, when the Cat falls below a certain reading or "threshold" the code is generating telling u that u need a new catalytic converter.
