P1526 Cadillac Code - Minimum Throttle Position Not Learned Conditions

Quick Answer

With the engine speed under 250 rpm, system volts over 10v, Engine Coolant Temperature (ECT) sensor input 41°F-212°F, Intake Air Temperature (IAT) sensor input over 41°F, VSS at 0 mph, Accelerator Pedal Position (APP) sensor input less than 15%, Minimum Closed Throttle position not learned, the Powertrain Control Module (PCM) detects the Throttle Position (TP) sensor 1 input was not between 0.24v-0.82v, and that the TP sensor 2 input was not between 4.2v-4.8v with the throttle valves commanded closed. Common causes include Faulty Throttle Position (TP) Sensor, Throttle Position (TP) Sensor harness is open or shorted, Throttle Position (TP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
