Comment Diagnostiquer
CodePage.commonMistakes
A very common mistake when diagnosing the P0605 code is automatically replacing the sensor or component mentioned in the code description without first testing it. Electrical issues, wiring damage, or vacuum leaks are frequently the true cause. Always use a multimeter and live data scanner to verify component failure before spending money on parts.
CodePage.faq
Can I drive with the P0605 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the P0605 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the P0605 code, your Mini will automatically fail an OBD2 plug-in emissions or smog test.
