Wondering on how to treat the error code P210C? Well, Parts Avatar is here to solve all you problems. Here we have written all that you need to know about the error code P210C. This error OBD-II code decreased engine performance generally determined as a throttle actuator "B" control motor circuit low. The throttle valve opening is monitored by the electronic throttle control system (ETCS). It can be seen that whenever the driver presses the accelerator pedal, a signal is sent to the engine control module (PCM) informing about the power the driver is requesting from the engine by the accelerator pedal position sensor (APP). In accordance with the PCM’ command, the throttle plate operates. When the PCM identifies that the throttle is not opening according to the requirements stated by the APP sensor, the code P210C is set by the PCM. Also, at times the engine may also go into the “limp home mode”. This limits the power available from the engine to avoid any unwanted acceleration.

The operations of the engine control module (ECM) along with the opening and closing of the throttle valve is controlled by the throttle actuator. All the power required for the throttle control motor is provided to the ECM through the throttle control motor relay. Also, the ECM plays the role of controlling the ON/OFF of the throttle control motor relay. As the ignition switch is switched on, the ECM transfers an ON signal to throttle control motor relay and battery voltage is provided to the ECM. on the other hand, when the ignition switch is switched OFF, the ECM transfers an OFF signal to throttle control motor relay and battery voltage is not provided to the ECM. The throttle position sensor (located on the throttle body) detects the opening angle of the throttle valve. Also, all the evaluation is provided to the ECM by the throttle position sensor. This evaluation helps the ECM to monitor the throttle actuator and regulate the throttle opening angle according to the driver’ entries.

What causes this problem with the Throttle Actuator B Control Motor Circuit Range Performance?

• The circuit to the throttle actuator open or short circuited
• A possible failure in the throttle actuator
• A malfunctioning powertrain control module

1. Throttle Actuator Connector - Hate the halts? See the error code P210C again and again? Well, it could be due to a faulty throttle actuator connector.

2. Electronic Throttle Control System (ETCS) - Is your car jerking? Observing a difficulty to maintain the optimum fuel economy? Check engine light on? Yes, all of this is caused due to a malfunctioning electronic throttle control system. Now you can get rid of the error code P210C with Parts Avatar. Log in now!
3. Throttle Valve - Because of a bad throttle valve the first thing you may notice is lack of power while accelerating and a downfall in the overall performance of the engine. Tune into Parts Avatar if you wish to restore or repair your throttle valve. 
4. Accelerator Pedal - Having problems with the Accelerator pedal? Well, it can be harmful as it triggers problems like throttle hesitation and an engine stalling. Don’t you worry, Parts Avatar has it all. A damaged accelerator pedal could end up being the root cause behind the error code P210C.
5. Accelerator Pedal Position Sensor (APP) - The accelerator pedal position sensor essentially informs the engine how fast or slow to drive when you press the gas pedal. If faulty, it can definitely lead an increased risk of accidents. Tune into Parts Avatar to get your now!
6. Powertrain Control Module - A number of irregular symptoms are likely to be experienced as soon as the PCM gets damaged. The powertrain control module enables the system and transmission to work in tandem. So a faulty PCM can affect not only a few parts but the functioning of the entire system. Tune into Parts Avatar for top notch sets of PCM.
7. Throttle Plate - A damaged throttle plate can cause electrical connection problems that further lead to an inaccurate or intermittent information to be relayed to the car’s computer. Restore or mend your throttle plate in order to get rid of these complications caused by the error code P210C.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P210C here:

Here are some steps which you should follow in order to diagnose this P210C fault code:

Firstly, it is advised to check for technical service bulletins (TSB) for your particular vehicle. The problem becomes easier to solve with a known fix put out by the manufacturer (also helps you save time and money). The throttle actuator B (TA-B) should be located in the vehicle. In front of the engine, on top of the engine, inside the wheel wells or against the bulkhead are a few places where one can generally locate the actuator. Now that it has been found, all the wirings and connectors should be visually inspected. Search for any traces of scraping, rubbing, bare wires, burn spots or melted plastic.

Next, the connector should be disconnected and pulled apart. Then carefully inspect the terminals (the metal parts) inside the connector. Any signs of green tint are likely to indicate corrosion. An electrical contact cleaner and a plastic bristle brush should be used to clean the terminals if required. Apply grease at places where the terminals connect after it has dried completely. The relays / connections to the relays along with an actuator are the most common causes and area of concerns triggering this code. Also, if the code reappears, the actuator and its associated circuits should be tested. Generally, there are 2 wires at each throttle actuator.

First and foremost, the harness going to the throttle actuator should be disconnected. Then using a digital volt ohm meter (DVOM) one end of the lead should be connected to one terminal. The remaining meter lead should be connected to the other actuator terminal (although it shouldn't be open or shorted). It is important to verify the resistance. The throttle actuator should be changed, if the actuator motor is either loose or short circuited (infinite resistance or no resistance/0 ohms). A DVOM should be employed, if the test is passed successfully to check that there is a 12V to the throttle actuator power supply (Red lead to the actuator power supply circuit, black lead to a good ground).

Making use of a scan tool (that can actuate) the throttle actuator, the actuator should be switched on. Also, If no 12 volts to the actuator is detected, mend the wiring from the PCM or relay to the actuator or also a malfunctioning PCM. if everything else is functioning in order, the ground at the throttle actuator should be checked. A test light should be linked to 12V battery positive (red terminal), while the other end of the test light to the ground circuit going to the throttle actuator circuit ground should be touched.

Next, a scan tool should be used to activate the throttle actuator to see if the test light flashes on every time the scan tool activates the actuator. Well, in any case if the test light fails to light up, this would likely signal towards a problematic circuit. And, if it does illuminate, the wiring harness connecting to the actuator should be twisted to see if the test light blinks (indicating an intermittent connection). Lastly, if all tests have been completed and still a code P210C is noticed, a failure in the throttle actuator should be suspected. Also, there are possibilities of a failed PCM as well. Still not sure? Well, we advise you to seek assistance from a certified automotive diagnostician. Also, the PCMs should be programmed or adjusted properly for an accurate installation.
