This error code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, especially those made since up to present. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another. This code, however, shows up more often among Ford and Nissan vehicles. The PCM powertrain control module, also known as ECM or engine control module in other vehicle makes receives input to determine when and how long it needs to operate the Throttle Actuator.
This input is in the form of voltage signal, which is received from the coolant temperature, intake air temperature, engine RPM, and air conditioning system pressure sensors. This error can be caused by mechanical problems, such as stuck throttle blade on the electrically driven throttle actuator.
Both electrical and mechanical problems cannot be overlooked in troubleshooting of this code, especially for intermittent conditions. Other symptoms include:. The symptoms of this code also usually depend on the severity of the condition, and also the problem could be either electrical or mechanical failure. Partial compensation usually means the engine has a fixed idle speed, which is usually around — RPM. Other possible causes include:. As with other error codes, diagnosing this code requires a scanner to document the code in the PCM.
The manufacturer provides a pinpoint test to verify the TAC signal, which must be used for the initial diagnosis. The technician will usually operate the accelerator pedal while monitoring the throttle position sensors and the TAC operation. Then, they will visually inspect the harness and connection to the TAC and look for signs of problems, and make sure the connector is on.Keepass
Replacement of the TAC assembly if it fails in all pinpoint test and the problem has been verified. As said in its definition, this code refers to a problem in the TAC unable to open and close the throttle plates. This means that the vehicle cannot be driven since it will not accelerate.

Dear readers, I have recorded this video during winter with hopes of having a feedback from Nissan Canada that I called but never got a follow-up from them.
Obviously I don't have this problem now but it hapened all winter. I'll be honest I sometimes had to move the car on short distances because after a snow storm here they have to clean the streets and the throttle doesn't always have time to heat. Could be ice within the throttle as well but who knows Maybe you can help me better with your advices or suggestions. This happened only during cold weather so far, except once lately with no apparent reason, but is really annoying.
There is also a wire that seems to be the block heater cable that is sort of used because it rubbed a lot against the engine protection plastic. Plus, I get bad gas mileage with my versa at all times in every condition, despite the good tires with ok pressure, good oil and new air filter. Could have a link. Anyway I said all I could think of, if anyone has any ideas before next winter arrives let me know, would be greatfull!
Should do it. Anyone can confirm what is dangerous and what's not, and if these things are what I think they are? Block heater cable? Cleaned my throttle body myself today and will get the electricity ground fixed this week.
Should help! Just a quick update, the throttle clean-up helped with the iddle and seemed to help with the engine sound but didn't really affect gas consumption. I will order a new O2 sensor and transmission fluid will be flushed and refilled this week-end, I'll keep the post updated for other people who have similar problems see how this did. Injector cleaner didn't make a difference so far, at least it didn't feel like it did.

You should also check that the spark plug gap is set properly. If your spark plugs look good, problems with your ignition system can also preventing a spark. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Parts or components should not be replaced with reference to only a P DTC.

The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Power supply for the throttle control motor is provided to the ECM via throttle control motor relay.
The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body.
The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to control the throttle actuator and monitor the throttle opening angle in response to driver inputs.

Home - About AutoCodes. Posted and Edit by AutoCodes.We recommend Torque Pro. This includes the motors that move the throttle plate. This moves the throttle plate to the desired position. The main component of this system is the throttle body, which is located between the intake manifold and the air filter.
It will have up to 2 motors that move the throttle plate and one or more throttle position sensors to let the PCM know where the throttle plate is located at all times.
Typically, when the command to the motors to move the plate does not correspond to the voltage signal sent back by the throttle position sensors TPScode P can be set. First things first: make sure you are not fighting yourself from the get go.
Take a look and see if there are any technical service bulletins TSB for your particular vehicle. Next, note if there are any other diagnostic fault codes. Insure that the battery is fully charged and not weak.
Weak batteries can cause the current at the electronic throttle motors to go up. Higher than normal under hood temperatures have been known to contribute to this as well. Diagnose current faults first, in the order in which they are stored. Look for any engine performance related issues, and diagnose those next. Also misdiagnosis occurs when this code is diagnosed when it is a stored code while other codes are active.
Typically, it is located between the intake manifold and the air filter. Once located, remove the tube that runs from the TAC system to the air filter. Once removed, visually inspect the throttle plates to see if they are clean and free of debris.
With the ignition switch off, you should be able to slowly rotate the throttle plate by pushing in on it. It should slowly rotate to the wide open position.
Clean behind the plate area by spraying a rag with carburetor cleaner and wiping it out. This only causes all the sludge to travel into the cylinders, possible coating the spark plugs and worse. Once completed, reattach the hose from the TAC system to the air filter housing. Clear the diagnostic trouble codes from memory, and see if this code returns.Ldac bluetooth cable
If it does not, then the sludge buildup was most likely your problem. They should be within 2 degrees of each other. If so, remove the air filter to TAC system hose once again and watch the throttle plates move as you perform this test. Anytime the throttle body is removed or replaced, the PCM will need to go through a idle system relearn procedure in order to relearn throttle plate position. Also, if a PCM must be replaced, it must be programmed in order it work on that particular vehicle.
At this point it is probably wise to consult with a trained automotive diagnostician. This site uses Akismet to reduce spam.P2101 Reduced Engine Power Message "Heres What to Do"
If it fails partially closed, then you'll be restrficting the air intake to the engine, affecting performance. You might be lucky and be able to tak it off and clean it to stop it sticking, but usually, by the time the error codes come up, the platic cogs of the motor rip their teeth off, so its a full replacement job.
The fuse usually goes in the fusebox too, so if you still get a persistent error code after replacing the motor, that needs replacing too Search for the other threads and there are plenty of photos If you do change it yourself, put a strong plastic bag over the rubber pipe so that you don't drop any bolts down it. I took the precaution and it saved me because I couldn't help but drop one of the three allen bolts, as its a fiddly job Replaced the throttle body at the weekend and the car is back on top form cheers for the help guys also just to note, i bought the new throttle body from euro car parts, next day delivery all in and thats for a brand new pierburg one as well andy.
