Nissan K25 lPG Forklift Throttle Position Sensor
Nissan K25 lPG Forklift Throttle Position Sensor
The Throttle Position Sensor (TPS) on a Nissan K25 LPG forklift is a crucial component that monitors the position of the throttle valve and sends this information to the engine control unit (ECU). This helps the ECU determine the appropriate fuel mixture and ignition timing for optimal engine performance.

Nissan Forklift Throttle Position Sensor Calibration
Nissan K25 lPG Forklift Throttle Position Sensor Calibration Instructions. To calibrate the throttle position sensor (TPS) on a Nissan K25 LPG forklift, follow these general steps:
- Locate the TPS: It’s usually mounted on the throttle body.
- Disconnect the Battery: Ensure safety by disconnecting the negative terminal of the battery.
- Remove the TPS: Unplug the electrical connector and remove the screws holding the sensor in place.
- Set the TPS: Position the sensor so that the throttle plate is fully closed and the sensor reads 0.0 volts.
- Adjust the Sensor: Use a multimeter to check the voltage readings at different throttle positions (e.g., 0.5V at half throttle, 4.5V at full throttle).
- Reinstall the TPS: Once calibrated, reinstall the sensor and reconnect the battery.

Nissan Forklift Throttle Position Sensor Symptoms
A faulty throttle position sensor (TPS) on a Nissan K25 LPG forklift can cause several issues. Here are some common throttle position sensor symptoms:
- Check Engine Light: The most common symptom is the illumination of the check engine light.
- Rough Idling: The engine might idle roughly or inconsistently.
- Poor Acceleration: You may notice a lack of power or poor acceleration.
- Stalling: The engine may stall or have difficulty maintaining idle speed.
- Erratic Throttle Response: The throttle may become unresponsive or overly sensitive.
- Reduced Fuel Efficiency: You might experience a drop in fuel efficiency due to improper air-fuel mixture.
For precise instructions, it is recommended to consult the vehicle’s service manual or contact a professional mechanic.
