On most modern 1.0 TCe, 1.3 TCe, and 1.5 dCi Renault engines, the sensor sits right above the transmission bell housing where the engine block connects to the gearbox. Unplug the electrical connector.
If the turbo has excessive shaft play, damaged wheels, or a seized VGT mechanism beyond cleaning, replacement is necessary. BorgWarner is the OEM supplier. Use a genuine or high-quality rebuilt turbo – cheap units often fail quickly. p158b renault
When the ECU logs code , it means the data packet or signal waveform coming from this sensor contains a checksum error, corruption, or signal drift . The ECU cannot trust the flywheel data, which interferes with timing calculations for fuel injection and ignition. Common Symptoms On most modern 1
Renault vehicles feature highly sensitive electrical systems. When a battery begins to degrade or drops below optimal voltage during engine cranking, the ECU drops communication with critical sensors momentarily. This creates a "ghost" or archived P158B code because the system loses track of the flywheel position during a low-voltage start. 2.

In a completely different context, "P158B" is also the model number for a rotary potentiometer used in older Renault models. Specifications: It is typically a 1kΩ linear resistance component.
