Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Monitor Result: Notes
Refer to detailed information (see CHECKING MONITOR STATUS ).
The test value and test limit information are described as shown in the following table. Check the monitor result and test values after performing the monitor driven pattern (refer to "Confirmation Monitor").
- Monitor Identification Data (MID) is assigned to each emissions-related component.
- Test Identification Data (TID) is assigned to each test value.
- Scaling is used to calculate the test value indicated on generic OBD II scan tools.
Heated oxygen sensor bank 1 sensor 2
| MID | TID | Scaling | Description of Test Value | Minimum Test Limit | Maximum Test Limit |
|---|---|---|---|---|---|
| $01 | $03 | Multiply by 0.001 [V] | Sensor voltage to define sensor status is Lean that is defined when sensor voltage is lower than this value | Sensor voltage to define sensor status is Lean | Sensor voltage to define sensor status is Lean |
| $01 | $04 | Multiply by 0.001 [V] | Sensor voltage to define sensor status is Lean that is defined when sensor voltage is lower than this value | Sensor voltage to define sensor status is Rich | Sensor voltage to define sensor status is Rich |
| $01 | $05 | Multiply by 0.001 [seconds] | Rich to Lean switch time | Minimum test limit | Malfunction criterion |
| $01 | $06 | Multiply by 0.001 [seconds] | Lean to Rich switch time | Minimum test limit | Malfunction criterion |
| $01 | $82 | Multiply by 0.001 [seconds] | Time of one cycle of sensor output | Minimum test limit | Maximum test limit |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
