What Does Code P2110 Mean?

throttle actuator circuit

The engine estimator (PCM) controls the Throttle Actuator Control (TAC) arrangement, also known equally the Electronic Throttle Control system (ETC). This includes the motors that movement the throttle plate. The PCM looks at the throttle position sensor to determine the driver's intent and then calculates the appropriate throttle response. The PCM accomplishes this past pulsing a voltage betoken to the TAC motors. This moves the throttle plate to the desired position.

The master component of this system is the throttle body, which is located between the intake manifold and the air filter. Unremarkably information technology will have one or more TAC / ETC motors to move the throttle plate inside, and one or more throttle position sensors to let the PCM know where the throttle plate is located at all times. When the command to the motors to move the plate does not correspond to the voltage bespeak sent back by the throttle position sensors (TPS), or if the amperage draw to the TAC motors is excessive, code P2110 tin exist fix.

What are the common causes of code P2110?

  • Faulty Throttle Actuator Control (TAC) module/Throttle Body (Very Common – can be caused by someone cleaning these throttle bodies who is unfamiliar with the correct cleaning process for the item vehicle – moves throttle plates incorrectly, damaging TAC motors)
  • Wiring to the Throttle Actuator Control (TAC) module is open or shorted
  • Poor electric connections at the Throttle Actuator Control (TAC) module
  • Failed PCM – unlikely

What are the symptoms of code P2110?

  • Malfunction Indicator Light "ON"
  • Electronic Throttle Control Indicator "On"
  • No throttle response – engine volition only idle

How do y'all troubleshoot code P2110?

Commencement, take a look and see if at that place are whatever technical service bulletins (TSB) for your particular vehicle. There may be a known fix put out past the manufacturer that tin save you from wasting fourth dimension and money.

Adjacent, note if in that location are any other diagnostic fault codes. Insure that the battery is fully charged and not weak. Weak batteries tin can cause the current at the electronic throttle motors to go upward. Higher than normal under hood temperatures accept been known to contribute to this likewise. Marginal/weak batteries take been known to prepare an intermittent P2110 fault code. Diagnose current faults get-go, in the social club in which they are stored. Misdiagnosis occurs when this code is diagnosed when information technology is a stored code, especially while other codes are active.

Next, locate the Electronic Throttle Command (ETC) organization on your particular vehicle. Unremarkably, information technology is located between the intake manifold and the air filter. Once located, remove the tube that runs from the ETC arrangement to the air filter. Once removed, visually audit the throttle plates to run across if they are make clean and free of debris. With the ignition switch off, you should be able to slowly rotate the throttle plate past pushing in on it. It should slowly rotate to the broad open position. If in that location is a considerable amount of sludge behind the plate, clean information technology while you are there, taking intendance not to impairment the throttle torso past pushing in very quickly or past doing then while the ignition switch is in the "Run" position (unless instructed to do and then past the vehicle manufacturer). Clean backside the plate surface area by spraying a rag with carburetor cleaner and wiping it out. DO Non SPRAY Annihilation INTO THE INTAKE! This only causes all the sludge to travel into the cylinders, possible coating the spark plugs, possibly causing a cylinder misfire and worse. In one case completed, reattach the hose from the ETC organization to the air filter housing. Perform an ETC system relearn procedure. Clear the diagnostic problem codes from retention, and come across if the P2110 code returns. If it does not, then the sludge buildup was most likely your problem.

If the code does render, check connections at both the PCM and the throttle body. Disconnect the negative battery cable earlier unplugging the connectors at the PCM or the throttle body. Once located, visually inspect the connectors and wiring. Look for scraping, rubbing, bare wires, burn spots or melted plastic. Pull the connectors autonomously and carefully audit the terminals (the metal parts) inside the connectors. See if they look burned or take a green tint indicating corrosion. Yous can go some electric contact cleaner and a plastic bristle castor at any parts shop if cleaning of the terminals is needed. If this is not possible, find some rubbing alcohol and an former molar castor to clean them with. After let them air dry, get some dielectric silicone chemical compound (same stuff they use for low-cal bulb sockets) and put some where the terminals come into contact. Clear the diagnostic problem codes from retentivity, and see if the P2110 code returns. If it does non, and so connection bug were almost likely your problem.

If the P2110 code returns, you may want to check the resistance of the ETC motors. With the ignition switch in the off position, disconnect the electrical connector at the TAC / ETC organisation. Locate the 2 pins that go to each motor on the throttle body. Using a digital volt ohmmeter (DVOM) set to ohms, find the resistance of each motor. Each motor should exist approximately between 2 and 25 ohms (check manufacturers specs for your vehicle). If the resistance is either too loftier or too low, the TAC/ETC system (throttle body) will need to be replaced.

If all tests take passed so far, you may want to check the voltage signals to each ETC motor, or resistance of the wiring between the ETC motors and the PCM. If any of these tests fail, it would indicate wiring repairs are needed between the PCM and the TAC organization / Electronic Throttle Control / throttle torso.

If all tests have passed to this betoken, and you continue to become a P2110 code, this would nigh likely bespeak a failed Throttle Torso Assembly, although a failed PCM could not exist ruled out until the TAC / ETC system had been replaced. Anytime the throttle body is removed or replaced, the PCM will need to go through a TAC / ETC organization relearn process in order to relearn throttle plate position. Also, if a PCM must exist replaced, it must be programmed in order it work on that item vehicle. At this point it is probably wise to consult with a trained automotive diagnostician.

Codes Related to P2110

  • P2101 – Throttle actuator control (TAC) organisation – range/operation problem – Usually P2101 goes forth with the P2110, as some of the same problems that set P2110 set the P2101.
  • P2101 is typically related to mechanical issues while the P2110 is nigh strictly electrical / motor issues.
