Here\u2019s how mechanics at Jorgio do that:<\/p><h3 class=\"wp-block-heading\">Step 1: The Voltage Test (Don&#8217;t Even Need Any Disassembly)<\/h3><p><strong>Find the TPP<\/strong> \u2013 Typically attached to the throttle body with a 3-wire connector.<\/p><p><strong>Turn the ignition ON (do NOT start the engine)<\/strong> \u2013 Touch the signal wire with the multimeter probe (usually the middle terminal).<\/p><p><strong>Look for a gradual transition<\/strong> \u2013 Ease on the accelerator pedal. Voltage should increase from ~0.5V to 4.5V smoothly.<\/p><p><strong>Pro Tip:<\/strong> If the needle jumps like a bad Wi-Fi signal, the resistive track on your TPP is shot.<\/p><h3 class=\"wp-block-heading\">Step 2: The Resistance (Hard Failures) Test<\/h3><p><strong>Unscrew the TPP<\/strong> \u2013 Turn to ohms on your multimeter.<\/p><p><strong>Check pin to pin<\/strong> \u2013 The resistance between any pin will be between 1k\u03a9 and 5k\u03a9 for the majority of TPPs. Infinite resistance? It\u2019s dead, Jim.<\/p><p><strong>Real-World Example:<\/strong> A 2023 study by SAE International showed that as many as 42% of &#8220;no-start&#8221; complaints in drive-by-wire vehicles had been misdiagnosed\u2014although the real villain was a $50 TPP.<\/p><h3 class=\"wp-block-heading\">When You Should Suspect Wiring (Not the TPP)<\/h3><p><strong>No power?<\/strong> Test for 5V reference voltage. No power? Check fuses or ECU issues.<\/p><p><strong>Check connectors<\/strong> \u2013 This is similar to TPP failure (a very popular dealer upsell).<\/p><p><strong>Stay Tuned:<\/strong> Mystery Behind Aftermarket vs. OEM Throttle Position Sensors.<\/p><p>Aftermarket vs. OEM TPS Potentiometer \u2013 Who Will Get You Home?<\/p><p>You\u2019re also looking at two options: a <strong>25 aftermarket <a href=\"https:\/\/www.nbzkjx.com\/es\/accelerator-throttle-position-potentiometer-sensor\/\">throttle <\/a>position potentiometer (TPP)<\/strong> or a <strong>1200 MOEPA RT<\/strong>.
