Full Product Name: Throttle Position Sensor (TPS)
OEM Part No.: 93356162
Fitment: Chevrolet Optra and selected Fiat models, aftermarket direct-fit replacement
Structure: 3-pin connector, matches OEM mounting holes and throttle shaft structure
Material: Plastic housing, precision resistive sensor element, OEM pin layout, electrical parameters compatible with original ECU signal specifications
Core Function: Real-time monitoring of throttle opening angle, transmits voltage signals to engine ECU, precisely controls fuel injection volume, idle speed and acceleration response for smooth driving
Common Faults: Internal resistor aging and wear → unstable idle, jerking, slow acceleration response, increased fuel consumption, check engine light (DTC codes P0121 / P0122 etc.)
Replacement Tips: Align correctly with throttle shaft slot, fasten screws with proper torque, perform idle speed adaptation after installation and verify normal signal voltage
