How to change out a throttle - Electric Currie EZIP 500 Scooter

Is it a twist throttle on the end of the handlebars or a thumb bar?
if it's a twist throttle on the end of a handlebar.....no, because the throttle will have to twist away from you if you put it on the left, so it's totally not practical. If it's a thumb bar, a general rewire of speed potentiometer behind the push bar for forward and reverse will change throttle over to the left push and reverse over to the right push.

P2110...Faulty Throttle Actuator Control Module
- Throttle Actuator Control Module harness is open or shorted
- Throttle Actuator Control Module circuit poor electrical connection

P2118 - Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.

Throttle Position Sensor/Switch (TPS) A Circuit Malfunction
The TPS (Throttle Position Sensor) is a potentiometer that is mounted to the throttle body. It detects the throttle blade angle. As the throttle blade moves, the TPS sends a signal to the PCM (Powertrain Control Module). Usually a three wire sensor: A 5 volt reference from the PCM to the TPS, a ground from the PCM to the TPS, and a signal return from the TPS to the PCM. The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is outside of normal operating range, P0120 will set. NOTE: The PCM knows that any large change in throttle position means a cooresponding change in manifold pressure (MAP). On some models the PCM will monitor MAP and TPS operation for comparison. Meaning that if the PCM sees a large percentage change in throttle position, it expects to see a cooresponding change in manifold pressure and vice versa. If it doesn't see this comparitive change, P0120 may set.

if you are just changing the grips, try to blow some air (with a compressor) into the end of it, they are held onto the throttle sleeve with glue. if you dont care about the old ones just cut them off but be careful to not slice thru the throttle sleeve inside

There are two cables leading to the throttle. Both have two pieces.
Cable 1 goes from the throttle about 12" long and connects to an adjustment piece joining it to cable2 which goes to the throttle body.
Cable 3 also goes from the throttle and is about 12" long and connects to and adjustment piece joining it to cable 4 which goes to the spring on the throttle body.
To change any of them you must loosen the adjustment piece until the ends can be removed from it.
Then to change cables 1 and 3 you have to remove the throttle cover on the grip. you will be able to see how they are removed. Then reverse these steps to install the new cable.
To change cables 2 and 4 in no more difficult but more time consuming as you will have to route these longer cables from the adjuster to where they connect to the throttle body.
When cables have been install and all parts reassembled you can carefully adjust the tension on the cables until the throttle responds the way you like it.
Hope this helps

Removal & Installation

1. Disconnect the negative battery cable.
   
2. Disconnect the throttle position (TP) sensor electrical connector.
   
3. Remove the screws and the TP sensor.
   

Throttle position (TP) sensor electrical connector



TP sensor


To install:

1. Install the screws and the TP sensor. Tighten screws to 7 inch lbs. (3 Nm)
   
2. Connect the throttle position (TP) sensor electrical connector.
   
3. Connect the battery ground cable.
   

You might try testing the tps. It may have a dead spot at the high end of the throttle opening. Make sure the resistance continues to change as you open the throttle all the way.

Throttle Position Sensor

Operation The throttle position sensor is a rotating type variable resistor that rotates with the throttle body-s throttle shaft to sense the throttle valve angle. As the throttle shaft rotates, the throttle angle of the sensor changes and the ECM/PCM detects the throttle valve opening based on the TPS output voltage.
Removal & Installation

1. Disconnect the negative battery cable.
2. Disconnect the sensor connector.
3. Remove the sensor retaining screws. Remove the sensor from its mounting.

To install:

1. Installation is the reverse of the removal procedure.

Testing 2.4L Engine

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 1 (sensor ground) and terminal 2 (sensor power).
3. Specification should be 3.5-6.5 kohm.
4. Connect and analog ohmmeter between terminal 1 (sensor ground) and terminal 3 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

2.7L Engine

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 2 (sensor ground) and terminal 1 (sensor power).
3. Specification should be 3.5-6.5 kohm.
4. Connect and analog ohmmeter between terminal 2 (sensor ground) and terminal 3 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 2 (sensor ground) and terminal 1 (sensor power).
3. Specification should be 1.6-2.4 kohm.
4. Connect and analog ohmmeter between terminal 2 (sensor ground) and terminal 3 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

3.5L Engine

its that throttle body you put on doing it try changing the mass air flow meeter and setting up the throttle pedel poshion switch this may sort you out,,,
if the throttle poshion switch is not set up it throws the gear box into a wobbely

TPS sensor on throttle body is a pentinlskjfhskljmeter hehe ...

The air intake tube is the plastic or rubber hose that connects the air filter box to the throttle body. It should be about 3-4 inches in thickness..... The motor is relitivly easy to change. Although, you will need to remove the throttle body to change because it is located on the botton of the throttle body. Let me know if you have any problems.
