P2138 Throttle/Pedal Pos Sensor Voltage Correlation Potential Causes of P2138 DTC 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.

replace battery , or replace remote

thats a bummer , why dont you list what you have tried or whats going on . better yet take it to a mechanic

Engine is probably stumbling because it is misfiring - it probably needs a tuneup (plugs, etc.).

Who did the work? With that much work done it should have come with some kind of warranty. I would take your car back to the person that did the work and ask them to take a look at it. Could be a fuel problem (fuel filter, pump, feed or return lines) or it could be a calibration that needs to be adjusted in your on-board computer. I would start with running a full diagnostic from a reputable company and see if it shows anything.

Is the battery as old as the car? If so, it's certainly the battery. OEM batteries on luxury cars last a surprisingly long time, but six years is usually the limit. Replacement batteries (in my experience) only last four years at most. So even if this isn't the original battery, it's time for a change. By the way, when a battery needs a charge or a replacement, it will be able to run accessories (such as a radio or cabin lights), but will not have enough power to crank the starter.

If you can play a DVD, the nav disc is dirty or worn. Try gently cleaning it with a flat screen tv cleaning solution and try again. If a DVD won't play, the read head in the player is either dirty or shot - you should have an A/V shop try to clean it, as replacing the unit is $$$$$.

The code insinuates that your purge valve has problems and probably needs to be replaced. Rather difficult to explain the repair but I did manage to find what you need to do on video. https://www.youtube.com/watch?v=08R_-QFGpDM

From: P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module. More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely). For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.

you must replace the multifunction switch its all one unit sorry

Most likely the problem is in the control. The washer switch is stuck or shorted out.

On the gas pedal assy Not the problem Move on to other issues Need a scan tool to check modules

You changed the spark plugs twice since 2006? Every three years-- I do mine Ignition Coils won't last 8 years,not all of them You have to look at scan tool data & road test Can not use a car for years & never work on it Your dealing with time in years & heat cycles Nothing at all to do with mileage Usually 100,000 miles you change oxygen sensors Yours are 9 years old,so they go based on time & again scope them, for switching times & look at the data Don't change your oil 3 times a year,you have engine wear Could be any number of things causing your cars issues
