GPS Receiver Error
Your vehicle's GPS receiver isn't communicating properly with the navigation system, similar to a phone losing its location signal. The car can't reliably determine its position or time, affecting features that depend on satellite data.
The ECU monitors the GPS receiver module for valid signal acquisition, data transmission, and time-to-first-fix performance. It checks that the receiver locks onto satellites, maintains communication protocol integrity, and provides position data within expected accuracy tolerances.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| GPS Signal Acquisition | Valid lock on 4+ satellites within 30 seconds | No signal lock or timeout exceeds threshold |
| GPS Module Communication | UART/CAN data received continuously at expected rate | No data frames or checksum errors detected |
Code B2205 is a low-severity fault. Your vehicle is generally safe to drive to a workshop for diagnosis. However, do not ignore it indefinitely — low-severity codes often indicate developing problems that become expensive if neglected. Book a diagnostic appointment within 2–4 weeks. If you notice any additional symptoms (rough running, power loss, unusual smells), treat it as higher priority.
Once the fault is repaired, B2205 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
