on 2024 Tesla Cybertruck Dual Motor AWD · AWD
What this code means
The power steering pressure sensor signal is outside its expected range. This sensor informs the PCM about steering load so it can adjust idle speed.
Symptoms
- Idle fluctuation when steering
- Check engine light on
- Rough idle at low speed
Common causes
- Faulty power steering pressure sensor
- Low or contaminated power steering fluid
- Wiring or connector fault
- Restricted power steering hose
Diagnostic steps
- Read sensor data with scan tool
- Compare signal to steering load
- Check fluid level and condition
- Inspect wiring and connector
