Good morning. I have a problem with my chery Tiggo 2009 1.6 I changed the la sonde d'oxygène over and over again. No, it still does not work. It always shows up in the test. What is the solution? Can you send me a wiring diagram or a way to solve this problem?

If the Chery Tiggo 2009 1.6 continues to show issues after repeatedly changing the oxygen sensor, the next step is to check for Diagnostic Trouble Codes (DTCs) using the X-431 scan tool. If DTC P0031 is still present, the ECM should be replaced. Additionally, the Immobilizer control module must be matched to the new ECM after replacement.

@Mr. Anderson Thank you for the answer, sir. If you are one of the company’s representatives, I ask you for after-sales service in Algeria. We suffer a lot from electricity problems and engine timing p0343
