Engine sensors Renault: problems by model and engine

Documented faults, from most to least important

Severity × frequency. Below each one, the Renault models it appears in.

- 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.
In Clio II, Clio III, Fluence, Kangoo I, Laguna II and Mégane I and 5 more models
- 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.
In Clio II, Kangoo I and Mégane I
- Medium severityFrequency: Occasional1.2 16vProbe and sensor faults (crankshaft position, throttle body)The 1.2 16V can fail because of specific probes or sensors, above all the crankshaft position sensor (TDC sensor) and the throttle body, with the engine warning light on or difficulty starting. Documented on the Clio II, Clio III and Kangoo I.
In Clio II, Clio III, Clio IV, Kangoo I, Modus and Twingo I and 1 more model
- Medium severityFrequency: Occasional1.0 SCe (B4D)Jerking, rough idle or warning light from sensors and ignition coilsThe 1.0 SCe can jerk, run unevenly or light up the engine fault warning light because of sensor faults (lambda sensor), ignition coils or injection management. It is a recurring but minority issue in the sources consulted, unrelated to a mechanical problem with the engine block.
In Twingo III
- Medium severityFrequency: Rare2.0 MR20DE / 2.5 QR25DEFaulty throttle body on the X-Trail T31 2.5 (QR25DE)Hella documents an X-Trail T31 2.5 (QR25DE, 2007-2014) with loss of power and irregular engine running caused by a throttle body defect, with intermittent voltage codes from the throttle position sensor.
