Function and Symptoms
The accelerator pedal assembly measures the driver’s throttle request and sends an electronic signal to the engine control unit (ECU). Modern pedals typically use dual redundant position sensors (two-channel potentiometers or Hall sensors) to provide safe, reliable signals. Common symptoms of a failing pedal unit include illuminated engine warning light, reduced engine power/limp mode, erratic or delayed throttle response, and stored fault codes such as P0120–P0123 or P0220.
Installation Recommendations
- Always disconnect the vehicle battery before starting removal to avoid short circuits and to protect electronic systems.
- Remove any trim panels or footwell covers to access the pedal assembly. Unplug the electrical connector and unbolt the pedal from its bracket.
- Install the new pedal in reverse order: secure mounting bolts to manufacturer torque specs, reconnect the electrical connector and reinstall trim panels.
- After installation, clear stored fault codes and perform a functional check: verify smooth pedal travel and correct ECU response. Some vehicles may require a throttle relearn or adaptation procedure via diagnostic equipment to restore optimum throttle mapping.
- If you are not experienced with electronic throttle systems, professional installation is recommended because incorrect fitting or wiring can affect vehicle safety and driveability.
Why This Part Fails
- Wear of internal potentiometers or sensor elements over time, leading to signal drift or loss of redundancy.
- Contamination from moisture, dust or corrosion in the connector, which disrupts electrical contacts.
- Mechanical damage from impact or improper handling during previous repairs.
- Wiring harness abrasion or connector faults causing intermittent signals and fault codes.
Diagnostics Tips
- Scan for fault codes (look for P0120–P0123, P0220). Clear codes, perform a road test and see if codes return.
- Visually inspect connector and wiring for corrosion, bent pins or damage before replacing the pedal.
- Measure sensor outputs with a multimeter or oscilloscope if available—many pedals use two complementary voltage signals (typically in a range around 0.5–4.5 V) that should change smoothly with pedal travel.
Cross-Reference And Search Tips
When searching online or in parts catalogs use the OE and Bosch references: 0280755167, 9671416880, 1601EA, 1601AG, and related numbers (280755167). Including vehicle model and year in the search increases the chance of an exact match.
Additional Notes
This part is a safety‑critical electronic component. Ensure secure electrical connections and correct mounting. After replacement, confirm full throttle response and absence of warning lights before normal use.
