Solution
1. Preparation
  • Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set, cleaning solvents, and safety glasses.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
2. Address Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Record any trouble codes and clear them from the system.
  • Re-test the vehicle to see if codes reappear during normal operation.
3. Fuel System Inspection
  • Check Fuel Pressure:
    • Connect the fuel pressure gauge to the fuel rail.
    • Start the engine and observe the pressure reading; it should meet manufacturer specifications (refer to service manual).
    • If pressure is low, check the fuel pump, filter, and lines for blockages or failures.
4. Inspect and Clean Components
  • Throttle Position Sensor:

    • Disconnect the TPS connector and use a multimeter to check voltage readings while moving the throttle.
    • Clean the TPS connector and housing with electrical contact cleaner if necessary; replace if faulty.
  • Idle Air Control Valve:

    • Remove the IACV from the intake manifold.
    • Clean the valve and its port with throttle body cleaner to remove carbon deposits.
    • Reinstall the IACV ensuring all gaskets are intact.
5. Test and Replace Components
  • If any components (TPS, IACV, or fuel pump) were found defective during inspection, replace them with OEM parts.
  • Reassemble any components removed during the inspection process, ensuring all connections are secure.
