WARNING: This page is about a different car, the 2005 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- While inspecting with check code 22, the measured value is displayed in both odometer and tripmeter segments of the odometer/tripmeter. Verify both readings.
CHECK CODE 22 DIAGNOSTIC PROCEDURES
| Check code 22 | Fuel level signal | ||
|---|---|---|---|
| STEP | INSPECTION CONDITION | DISPLAY | ACTION |
| 1 | Select check code 22 with the fuel gauge sender unit connector disconnected. | 370 - 430 | Go to the next step. |
| Except above | Replace the instrument cluster. | ||
| 2 | Connect terminals 2T and 2R, 2T and 2P of the instrument cluster. | 000 - 007 | Go to the next step. |
| Except above | Replace the instrument cluster. | ||
| 3 | Using the SST (Fuel and thermometer checker) or resistor, input 80 ohms between instrument cluster terminals 2T and 2R, and 2T and 2P. | 071 - 089 | Go to the next step. |
| Except above | Replace the instrument cluster. | ||
| 4 | Using the SST (Fuel and thermometer checker) or resistor, input 160 ohms between instrument cluster terminals 2T and 2R, and 2T and 2P. | 147 - 173 | Go to the next step. |
| Except above | Replace the instrument cluster. | ||
| 5 | Using the SST (Fuel and thermometer checker) or resistor, input 240 ohms between instrument cluster terminals 2T and 2R, and 2T and 2P | 221 - 259 | Inspect the fuel gauge sender unit. |
