GM Daewoo E-TEC II 1.4 and 1.6 16v (Lacetti/Optra and Aveo de primera generación)Engine sensorsLambda sensor
Lambda sensor faults on the 1.4 / 1.6 16v E-TEC II
Why this rating?
Low severity: A nuisance or wear. It does not immobilise the car or damage other parts.
Frequency occasional: Two independent publications, Auto Świat (on the Lacetti, 2007) and Autokult (on the Aveo, 2012), cite it as a fault that occurs, with no percentages or statistics. That is why we leave it as occasional and not higher.[1][2]

Other 1.4 / 1.6 16v E-TEC II faults
- Medium severityFrequency: OccasionalCylinder head and blockFaulty valves and ignition faults in the first units (2004-2005)In the first units of the Lacetti 1.4 16v, from 2004-2005, the Polish press documents ignition faults caused by faulty valves, which were repaired under warranty. If they appear outside warranty, the repair can be costly.
- Low severityFrequency: RareLubricationOil consumption and oil leaksThe Polish press mentions oil leaks on the Lacetti 1.4 16v and on the Aveo (crankshaft seal), and high consumption on some Lacettis. These are isolated cases: most owners who comment notice no consumption.
More faults with the engine sensors on other engines and cars
- High severityFrequency: Occasional2.0 DTI and 2.2 DTIVP44 injection pump and air mass meter failureGerman Wikipedia documents recurring failures of the Bosch VP44 injection pump and the air mass meter in the early years of this engine. An owner testimony for this engine describes the pump being replaced at 192,500 km, at a cost the owner calls «prohibitive».
- Medium severityFrequency: Common2.0 TDIClogged particulate filter or faulty pressure sensorThe 2.0 TDI's particulate filter clogs if the car mostly makes short journeys, because it never gets to regenerate; sometimes the fault is just the differential pressure sensor. Cleaning it costs around €200 and replacing it, €800 to €3,000.Repair (garage): €800–€3,000
- Medium severityFrequency: Common1.4 and 1.6 8vCrankshaft position sensor failure (TDC sensor)The crankshaft position sensor (capteur PMH, or TDC sensor) appears repeatedly in the reliability sources for the Clio II, the Kangoo I and the Dacia Logan I with this engine, with hard cold starting or stalling as the main symptoms. It is a cheap part, but the failure can leave you stranded.
- Medium severityFrequency: Common1.2 8vCrankshaft sensor (TDC) and other engine sensor failureThe sensors, including the crankshaft TDC pickup, are the category that adds the most cases in the entries for the 60 hp 1.2 8v: 17 out of 74 opinions on the Clio II (23%) and 19 out of 80 on the Twingo I (24%). The entries do not detail how the fault shows itself.
- Medium severityFrequency: Common1.4 and 1.6 16vCrankshaft position sensor failureThe crankshaft position sensor (capteur PMH) appears repeatedly in the reliability sources for almost every generation with this engine, with hard cold starting, stalling or the car cutting out unexpectedly. It is a cheap part, but the failure can leave you stranded.
- Medium severityFrequency: OccasionalBMW B57AdBlue/SCR system fault (NOx sensors, heater and pump)A specialist garage considers the B57's AdBlue/SCR system the fault that most often leaves cars immobilised: a NOx sensor, the quality sensor, the heater or the pump usually fails, and topping up the tank rarely stops the countdown of remaining starts.
