'Upstream lambda probe' error presentIdentify and eliminate the cause of the anomaly.Continue to Step 5
1EXHAUST SYSTEM LEAKS CHECKAll OKProblems metOperation
Look and listen to check the exhaust system from the cylinder head outlet to the downstream lambda probe.Check that there are no leaksContinue to Step 2There are leaksRestore the exhaust system seal and replace the affected parts if necessaryContinue to Step 5
2ROAD TEST TO CHECK MIXTURE STRENGTHAll OKProblems metOperation
1.2 16v 1.6 16v 2.4 20vRoad test the vehicle and check the mixture strength in the 1st and 2nd closed loops using the diagnostic equipment.Check that the activation is correctContinue to Step 3The 1st closed loop activation is not correctSee table   Z56 
The 1st closed loop activation is not correctSee table   Z58 
1.8 16vRoad test the vehicle and check the mixture strength in the 1st and 2nd closed loops using the diagnostic equipment.Check that the activation is correctContinue to Step 3The activation is not correctSee table   Z56 
3CHECKING INLET AND EXHAUST SYSTEM SEALAll OKProblems metOperation
Check the exhaust system visually and by listening, to check that there are no leaks from the cylinder head outlet to the upstream lambda sensorContinue to Step 4Seal not correctRestore system seal and replace the affected parts if necessaryContinue to Step 5
4REPLACING THE CATALYZERAll OKProblems metOperation
Replace the catalyzer Op.   1080B62  Continue to Step 5
5DELETING AND CHECKING ERRORAll OKProblems metOperation
Use a tester to cancel the errors in the control unit.Carry out a road test and ensure the error does not recurContinue to Step 6The fault persists, it is the first time that this step has been reached and the catalyzer has not yet been replacedContinue to Step 0
The fault persists, it is the first time that this step has been reached and the catalyzer has not yet been replacedContact Technical Support for further information on the problem
6CHECKING CORRECT OPERATIONAll OKProblems metOperation
Check that the fault is no longer presentEnd of diagnosis
