Think, he told himself. Voltage drop. But the battery is new.
Over time, carbon buildup can block the airflow path, preventing the throttle valve from reaching the exact position requested by the ECM. p158b renault
The P158B code may appear with or without noticeable drivability issues. However, when symptoms are present, they typically include:
Short answer:
When the P158B Renault fault code appears, it can cause a range of symptoms, including:
Corroded, broken, or shorted wiring in the harness connecting the ECM to the throttle body. LeBlanc arrived at 7:00 AM sharp
This is a known phenomenon with some ELM327-based scanners. It is possible for one scanner to detect the code while another, often a more professional or original dealer tool, does not. This does not necessarily mean the fault is absent, but rather that the scanners have different sensitivities or access different memory areas of the ECU.
When this code triggers, the driver will usually notice immediate, tangible changes in vehicle behavior. Because air regulation directly impacts combustion, look out for these telltale signs: Voltage drop
If you own a modern Renault (such as the Megane, Scenic, Clio, Captur, or Talisman) equipped with a common-rail diesel engine (particularly the 1.5 dCi K9K or 1.6 dCi R9M), you may eventually encounter the dreaded check engine light accompanied by a diagnostic trouble code (DTC): .
