The ECU compares the two sensor signals in real time — if they diverge by more than a calibrated threshold, the ECU detects a sensor fault and activates limp mode (typically limiting throttle to 10–15% opening). This prevents uncontrolled throttle opening from a single sensor failure. A corroded TPS signal pin causes the two sensor readings to diverge, triggering limp mode even when the throttle body itself is functioning correctly.\u003c\/p\u003e\n\n\u003ch3\u003eFault Codes This Connector Fixes\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eP0120–P0124:\u003c\/strong\u003e Throttle Position Sensor A Circuit Faults\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eP0220–P0224:\u003c\/strong\u003e Throttle Position Sensor B Circuit Faults\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eP2101:\u003c\/strong\u003e Throttle Actuator Control Motor Circuit Range\/Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eP2104:\u003c\/strong\u003e Throttle Actuator Control System — Forced Idle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eP2135:\u003c\/strong\u003e Throttle\/Pedal Position Sensor A\/B Voltage Correlation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eP2119:\u003c\/strong\u003e Throttle Actuator Control Throttle Body Range\/Performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My car goes into limp mode with P2135 — is this the connector?\u003c\/strong\u003e\u003cbr\u003eA: P2135 (TPS A\/B voltage correlation) is almost always caused by a connector fault rather than a failed throttle body. A corroded TPS signal pin causes the two sensor readings to diverge, triggering P2135 and limp mode. Clean the connector pins with electrical contact cleaner and re-test before replacing the throttle body ($150–$400).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Are terminals included?\u003c\/strong\u003e\u003cbr\u003eA: Yes, terminals are included with all variants.\u003c\/p\u003e","brand":"Cable Parts Online","offers":[{"title":"Male","offer_id":47831543185653,"sku":"14:202642826#Male","price":11.2,"currency_code":"USD","in_stock":true},{"title":"Male 15CM","offer_id":47831543251189,"sku":"14:200004890#Male 15CM","price":17.2,"currency_code":"USD","in_stock":true},{"title":"Female","offer_id":47831543218421,"sku":"14:200004889#Female","price":12.5,"currency_code":"USD","in_stock":true},{"title":"Female 15CM","offer_id":47831543283957,"sku":"14:200004891#Female 15CM","price":18.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3494\/0149\/files\/Sbcd42122ed7c4beab7176569b281fed3Y.webp?v=1773629291","url":"https:\/\/www.csldmcml.com\/products\/6-pin-diagnostic-throttle-body-connector-female-oem-obd-throttle-harness","provider":"Cable Parts Online","version":"1.0","type":"link"}
