Keep the engine control module reading throttle input accurately with the Standard Ignition Throttle Position Sensor TH422. It installs as a direct-fit replacement for the 2000-2002 Honda Passport, 2002-2004 Isuzu Axiom, 2000-2004 Isuzu Rodeo, 2001-2003 Isuzu Rodeo Sport, and 2000-2002 Isuzu Trooper, giving these applications a fresh sensor when the original has worn or begun sending an erratic signal.
Because these symptoms can have other causes, diagnose the fault before replacing. When the throttle position sensor is confirmed as the problem, this TH422 unit replaces it and helps restore an accurate throttle-position signal to the engine management system.
