Product Details

Walker Products has supplied fuel system and engine management components since 1946, with manufacturing and engineering support aimed at meeting OEM standards and specifications. The Walker Products 200-1438 throttle position sensor is part of that engine sensor lineup and is built for accurate throttle body signal reporting in select Saturn applications. This part cross-references 5S5380 and TH0251 for the same application.

Compatible With 2003-2004 Saturn Ion and 2004 Saturn L300, this sensor supports proper throttle signal feedback to the engine control system. Walker Products 200-1438 is a practical replacement choice when servicing throttle response or sensor-related drivability concerns on these vehicles.

Common Issues This Part May Address

• Erratic or delayed throttle response
• Throttle position sensor fault codes
• Unstable idle caused by incorrect throttle signal input
• Hesitation during acceleration
• Driveability problems related to throttle body signal loss

Installation Notes and Tips

Verify connector shape, terminal count, and throttle body mounting style before installation. Inspect the throttle body connector and wiring for corrosion, bent pins, or damaged locking tabs before connecting the new sensor. Because this unit is non-adjustable, install it in the correct orientation and confirm the throttle body linkage moves smoothly after replacement.
