It uses a fixed installed output to match OE calibration, helping maintain accurate throttle signal feedback for drivability and emission control.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFemale connector with a plug-in design for straightforward electrical connection\u003c\/li\u003e\n\u003cli\u003e3 female bullet terminals for the specified application\u003c\/li\u003e\n\u003cli\u003eFlexible polyimide film or ceramic-based circuit construction for dimensional stability\u003c\/li\u003e\n\u003cli\u003eNoble metal contact materials to support low resistance and long service life\u003c\/li\u003e\n\u003cli\u003eIntegral rotor bearings and return springs for consistent throttle movement\u003c\/li\u003e\n\u003cli\u003eEnd-of-line testing with thousands of data points to verify output voltage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Product Overview\u003c\/h2\u003e\u003cp\u003eThe Standard Ignition TH27 throttle position sensor is engineered for vehicles that need accurate throttle angle reporting to the engine control system. By maintaining a specific installed output rather than using an adjustable consolidated design, TH27 helps preserve OE-style signal behavior. This matters on applications such as 1982-1986 Buick Century, 1982-1986 Chevrolet Celebrity, 1984-1986 Jeep Cherokee, and 1982-1985 Chevrolet S10, where stable TPS output supports smooth throttle response and proper fuel management. Standard Ignition TH27 is also listed for 1982-1984 Pontiac Firebird and 1983-1985 GMC S15 Jimmy applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references Gates 38003 and Walker Products 200-1003 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eErratic throttle signal readings\u003c\/li\u003e\n\u003cli\u003eHesitation or poor throttle response\u003c\/li\u003e\n\u003cli\u003eRough idle caused by inconsistent TPS output\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to throttle position feedback\u003c\/li\u003e\n\u003cli\u003eDriveability issues on older emission-controlled vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify connector style, terminal count, and mounting alignment before installation. The TH27 uses a female plug-in connector with 3 female bullet terminals, so the harness and sensor interface must match the vehicle’s original configuration. Confirm throttle linkage movement is smooth and inspect the throttle body for wear or contamination before final setup. For fitment verification, match the vehicle application exactly, including model year and engine management configuration.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eStandard Ignition maintains manufacturing quality control from component selection through finished product testing. Each sensor is validated at the end of the line to confirm output voltage performance, and the circuit design uses stable materials to help reduce electrical drift over time.\u003c\/p\u003e","brand":"Standard Ignition","offers":[{"title":"Default Title","offer_id":52827889008821,"sku":"FBHK-TH27","price":63.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/SI_TH27_Fro.jpg?v=1784610841","url":"https:\/\/www.partcatalog.com\/products\/standard-ignition-th27-throttle-position-sensor","provider":"PartCatalog","version":"1.0","type":"link"}
