Tip

Throttle Actuator Control - drive by wire


1.5) TAC - Throttle Actuator Control
What is it? Some vehicles have indirect throttle control "drive by wire". Instead of the accelerator pedal position being conveyed directly to the throttle plate by cable linkage, it is detected by an electrical sensor and this is fed to the ECU. The ECU in turn sets the position of the throttle plate appropriate to the sensed position using an electric motor. The throttle plate position is, in turn, checked by the throttle position sensor and this signal is sent to the ECU to confirm that the requested throttle plate setting and its recorded position are in agreement.

Where is it located? The first part of the TAC is located on the inner wing/fender and consists of rotary device to which the accelerator cable is attached; the degree of rotation (pedal depression) is detected electrically and this is signalled to the ECU. The second part of the TAC is located on the throttle body and acts on the throttle plate shaft.

Symptoms of a faulty TAC
Associated OBD2 error codes DTCs: P0120, P0124, P1516; P2102, P2103;P2111 - P2118

  • Sudden power loss/limp home: If the ECU detects any fault with the throttle actuator control directly or with the position feedback via the TPS it engages an immediate engine shut-down to either idle speed or limp-home speed.

How to fix? The TAC is part of complex systemand the failure of the TPS has to be eliminated first as a possible source of error. A simple electrical connection failure can also give rise to the shutdown so all associated connections should be checked to ensure that they are clean and bright to allow electrical continuity.

2kd-ftv engine problem p1226 fuel line malfunction


Possible causes of the P1226 code include:
  • Faulty electric throttle control actuator, throttle position sensor 2
  • Faulty throttle control actuator harness is open or shorted, throttle position sensor 2
  • Electric throttle control actuator circuit has poor electrical connection, throttle position sensor 2
To nail down the exact cause of the code, do a visual inspection for lose wires and connections at the sensor, or damage to the sensor body itself. If no problems with the wiring and connections are detected, a worn/damaged electric throttle control actuator is likely at fault. Signs of a bad throttle control actuator include erratic acceleration, and unresponsive throttle, and poor fuel economy.

P0508 code on 2001 Honda CR-V how do I troubleshoot


Hello,

P0508 = Idle Air Control System Circuit Low

Symptoms:
Engine Light ON (or Service Engine Soon Warning Light) - Engine hard to start - Rough or erratic idle speed.

Causes:
Dirty throttle body - Electric throttle control actuator misadjusted or damaged - Faulty Electric throttle control actuator - Intake air leak - Poor electrical connection to the Intake Air Control (IAC) valve.

Solution:
If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.


I hope this helps!

My 2003 chevy truck goes into limp mode and pulls code PO220.Where is the tps sensor located?


Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- No throttle response Possible Causes - Harness or connector (The TP sensor circuit is open or shorted.)
- Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP) P0220 Description Electric Throttle Control Actuator consists of throttle control motor, throttle position (TP)sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
When is the code detected? An unexpected voltage from the TP sensor is sent to ECM.

When i turn on heater or fan engine revs over 3000 rpm


Idle Air Control Valve Pintle may be bad If you disconnect the IAC and the problem ceases it can point to this being the problem.: Removal & Installation 3.5L Engine To Remove:
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the fuel injector sight shield.
  3. Drain the cooling system.
  4. Remove or disconnect the following:
    • The air cleaner intake duct. Figure of IAC and TPS electrical connectors disconnected. aurora_g1.gif

    • The idle air control (IAC) valve and throttle position (TP) sensor electrical connectors. Figure of cruise control and throttle control cables removed from throttle lever. aurora_g2.gif

    • The cruise control cable and throttle control cable from the throttle body lever.

    • The throttle body coolant hoses.
    • The throttle control cable bracket, leaving the throttle and cruise cables connected.
    • The upper nut holding the throttle body to the intake manifold.
    • The throttle body assembly.

Low idle, stalls when put into gear, engine light on, code reader finds p0506 what is the most likely cause. the ICV recall was just done, this problem was happening before the recall work was done


When is the code detected? The idle speed is less than the target idle speed by 100 rpm or more.
Possible Causes - Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve
Possible Solution If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.
