Toyota Forklift Error Code E-24: Fixing Fuel System Issues with Vibe Forklifts' Aftermarket Toyota 4Y Parts

Error Code E-24 on a Toyota forklift is typically related to fuel system malfunctions, particularly on models equipped with the Toyota 4Y engine. These fuel system issues can result in poor performance, engine stalling, or difficulty starting. Whether you're troubleshooting a faulty throttle position sensor or replacing a clogged fuel injector, Vibe Forklifts is your go-to nationwide source for aftermarket Toyota 4Y engine parts at competitive prices with fast delivery.

1. Faulty Throttle Position Sensor (TPS) – Inaccurate throttle readings can trigger this error.
2. Clogged or Failing Fuel Injectors – Dirty injectors can lead to fuel starvation and performance issues.
3. Malfunctioning Fuel Pressure Regulator – Incorrect fuel pressure disrupts the engine's air-fuel ratio.
4. Wiring or Electrical Issues – Damaged connections to fuel system components can cause error signals.

Diagnosis:

• The TPS may be worn out or sending incorrect signals to the ECU.
• Common symptoms include erratic acceleration or sluggish throttle response.

Repair Instructions:

1. Locate the TPS on the throttle body.
2. Use a multimeter to test the sensor’s voltage output.
3. If readings are outside the manufacturer’s specifications, replace the TPS.

Tools Needed:

• Multimeter
• Screwdrivers
• Socket wrench set

Parts Needed:

• Throttle Position Sensor (TPS) – Toyota 4Y engine-equipped forklifts use different TPS part numbers depending on the model and series. For example: 
  • 57510-26600-71 – Compatible with Toyota 8FGU15
