- Accelerator Pedal Position harness is open or shorted
- Accelerator Pedal Position circuit poor electrical connection
First diagnose P1273 BUICK code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P1273 BUICK code
Labor: 1.0The cost of diagnosing the P1273 BUICK code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P1273 BUICK code detected?The Engine Control Module (ECM) compared the signal from both Accelerator Pedal Position (APP) sensors and detected a voltage difference.
P1273 BUICK Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1273 BUICK MeaningThe Accelerator Pedal Position (APP) sensors are located within the Throttle Actuator Control (TAC) module assembly. The TAC module assembly is mounted to the accelerator pedal bracket. There are 3 individual APP sensors within the TAC module. Three separate signal circuits, low reference circuits, and 5-volt reference circuits are used in order to determine the accelerator pedal position. The APP sensor signal voltages increase when the accelerator pedal is depressed.
