NTK TH0157 Throttle Position Sensor

Throttle Position Sensor for Nissan and INFINITI

NTK TH0157 is a throttle position sensor built for throttle body mounting and direct signal feedback in the engine management system. It is a fitment-based replacement for select Nissan Frontier, Nissan Xterra, Nissan Pathfinder, and INFINITI QX4 applications.

Key Features

• Throttle body mounted design for direct throttle input sensing.
• Plastic sensor housing with a rectangular female connector.
• Blade terminals with 6 terminal contacts for secure electrical connection.
• NTK TH0157 is part of the NTK Throttle Position Sensor line.
• Cross-references Standard Ignition TH230 and Beck/Arnley 158-0611 for the same application.

Detailed Description

NTK TH0157 is a throttle position sensor engineered for vehicles that rely on accurate throttle angle feedback for fuel and drivability control. The sensor mounts on the throttle body and uses a rectangular 2-connector layout with blade terminals to match the original electrical interface on supported applications. This part number, TH0157, is listed for 1996-2000 Nissan Pathfinder, 1999-2004 Nissan Frontier, 2000-2004 Nissan Xterra, and 1997-2000 INFINITI QX4 applications, including the 2000 QX4 note to 12/1999.

NTK draws on OE sensor experience and subjects its technical sensors to thermal shock, vibration, and OBD verification testing. That background supports consistent signal output and OE-level specification alignment for import and domestic vehicle coverage. For buyers searching for a Nissan Frontier throttle position sensor or a Nissan Pathfinder throttle position sensor, TH0157 provides a direct replacement option from NTK.

Common Issues This Part May Address

• Erratic throttle response or delayed acceleration input.
• Unstable idle caused by incorrect throttle angle reporting.
• Check engine light related to throttle position sensor faults.
• Driveability concerns from inconsistent sensor voltage output.
• Replacement needs after sensor wear or electrical failure.

Installation Notes and Quality

Verify connector style, terminal count, and throttle body mounting before installation. Confirm the vehicle application and note-specific coverage for the 2000 INFINITI QX4 before ordering. The sensor is not listed with mounting hardware or a mounting bracket included.

NTK states that its sensors are manufactured to meet or exceed OE specifications and are validated through thermal shock, vibration, and OBD testing. TH0157 is part of NTK's technical sensor lineup, backed by the brand's OE supplier experience and broad aftermarket coverage.
