DTC NO.
P0031
DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on and record and erase DTC.
• Start engine and warm it up to the normal operating temperature.
• Turn ignition switch off and wait at least 10 seconds.
• Start engine and keep the engine speed 2000 RPM for at least 1 minute.
• Let engine idle for 2 minutes, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 03 Electronic Engine Controls for more information.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.

Do you have a question about the Tiggo 2009 and is the answer not in the manual?
Questions and answers
Starting and cutting off
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
Is it possible to have a Picture of rocker arms (chery tigoo 1.6 plastic timing belt)
