Where is the ETB motor?

P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes: Diagnostic Aids: This DTC is an informational DTC and may be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first.

P2107 - Throttle Actuator Control (TAC) Module Processor Description: The electronic throttle control (ETC) area of the powertrain control module (PCM) failed the self-test. The concern could be the result of an incorrect throttle position (TP) command, or TAC motor wires shorted together. Possible Causes:

• TAC motor wire shorted together
• TAC motor circuit wires short to PWR
• Damaged electronic throttle body (ETB)
• Damaged PCM

Diagnostic Aids: A TAC motor circuit PID reading may indicate a concern, if available. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DV .
P2111 - Throttle Actuator Control (TAC) System - Stuck Open Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a greater angle than commanded. Possible Causes:

• Binding throttle body, stuck open
• TAC motor circuits are cross-wired
• TAC motor harness circuits are shorted together
• Damaged PCM

Electronic Throttle Actuator Control (TAC)
The electronic TAC is a DC motor controlled by the PCM (requires 2 wires). The gear ratio from the motor to the throttle plate shaft is 17:1. There are 2 designs for the TAC, parallel and in-series. The parallel design has the motor under the bore parallel to the plate shaft. The motor housing is integrated into the main housing. The in-series design has a separate motor housing. Two springs are used; one is used to close the throttle (main spring) and the other is in a plunger assembly that results in a default angle when no power is applied. The force of the plunger spring is 2 times stronger than the main spring. The default angle is usually set to result in a top vehicle speed of 48 km/h (30 mph). Typically this throttle angle is 7 to 8 degrees from the hard stop angle. The closed throttle plate hard stop is used to prevent the throttle from binding in the bore (~0.75 degree). This hard stop setting is not adjustable and is set to result in less airflow than the minimum engine airflow required at idle. For additional information, refer to Torque Based Electronic Throttle Control (ETC) in this section.

Electronic Throttle Body (ETB) Position Sensor
The ETB position sensor has 2 signal circuits in the sensor for redundancy. The redundant ETB position signals are required for increased monitoring. The first ETB position sensor signal (TP1) has a negative slope (increasing angle, decreasing voltage) and the second signal (TP2) has a positive slope (increasing angle, increasing voltage). During normal operation the negative slope ETB position sensor signal (TP1) is used by the control strategy as the indication of throttle position. The 2 ETB position sensor signals make sure the PCM receives a correct input even if 1 signal has a concern. There is 1 reference voltage circuit and 1 signal return circuit for the sensor. For additional information, refer to Torque Based Electronic Throttle Control (ETC) in this section.

Hi there

This is related to the ETB motor and you need to make sure if its working. Try the following

ETB motor error

1 Clean the ETB unit intermediate

connector, J36. If the connector is

damaged, replace it.

2 Reconnect the connetors J38 for the

ETB motor and J1111 on the DC

controller PCB.

3 Replace the ETB motor.
4 Replace the DC controller PCB.

Dear George

As with my experience the ETB lasts for a long time. But still if you want i will instruct you but right now i do not have pictures, but i will try to post it later for your reference.

Follow these steps

1. Remove top cover
2. Remove the left side cover and you can see the connection of ETB motor and sensor wires Usually Purple color with white connector on bottom.
3. remove the connection and carefully unlock the ETB from the holders.
4. replace the one you have in the same fashion as you removed.

DO RATE MY SOLUTION

The error says that "The transfer rollers in the ETB are not
engaged."

If replacing the ETB(electronic transfer belt) doesn't fix the problem, your printer is going to need a technician. Problem could be poor seating of the cables on the ETB motor or the 'transfer-roller separation solenoid or the DC Controller.
It could be a bad ETB motor or solenoid or DC Controller or high voltage power supply.
This isn't something that is going to be fixed by email.

I hope you have a service contract for your printer.

Replacing the ETB (transfer Kit)
Replace the ETB when a REPLACE TRANSFER KIT message displays on the control panel.
1. Turn the printer off.
2. Open the top and front cover.
3. Lower the ETB by pulling the green handle at the top of the unit downward.
4. Press the small blue latches located on either side of the bottom of the ETB and lift the unit out
of the printer.
5. Install the new ETB.
6. Close the front and top covers.

59.9 is a ETB motor error.
You are going to have to replace the motor or the DC controller which drives the motor.
If you are not a tech, now is the time to call one.

Error 59.90 refers to the problem with the transfer belt motor. Try to open the front cover and reseat the ETB, sometimes it helps. If the error appears again, probably you'll have to change the ETB.

That depends what kind of printer you're dealing with. In general, you should just open a front cover. Then release the ETB from the rest of the machine. Look for two blue handles to release the ETB. Replace the ETB and make sure the printer detects the new ETB. If the printer don't detects the new ETB, try to restart the printer or reset the ETB-counter in -Configue device--->resets----->reset supplies----->NEW ETB.
