Código de avería P0101 – This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles (Nissan, Chevrolet, GMC, Mercedes, VW, Toyota, Mazda, BMW, Ford, Audi, Honda, etc.). Although generic, the specific repair steps may vary depending on make/model. The MAF (mass air flow) sensor is a sensor mounted in a vehicle’s engine air intake tract downstream from the air filter, and is used to measure the volume and density of air being drawn into the engine. The MAF sensor itself only measures a portion of the air entering and that value is used to calculate the total volume and density of air being ingested.

Solución del código P0101
Possible diagnostic and repair steps include: Visually inspect all MAF sensor wiring and connectors to make sure they are intact, not frayed, broken, routed too close to ignition wires/coils, relays, motors, etc. Visually inspect for any obvious air leaks in the air intake system Visually *closely* inspect the MAF sensor wires or film to see if you can see contamination such as dirt, dust, oil, etc. If the air filter is dirty, replace it Carefully clean the MAF using MAF cleaner spray is generally a good DIY friendly diagnostic/repair step If the air intake system has a mesh in it, make sure that is also clean (VWs mainly) Loss of vacuum to the MAP sensor can trigger this DTC A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor. Use a scan tool to monitor real-time sensor values from the MAF sensor, O2 sensors, etc. Check for Technical Service Bulletins (TSBs) for your particular make/model in case of known issues on your vehicle The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON. A high resistance on the ground circuit of the MAP sensor can cause this DTC to set Do an exhaust backpressure test to determine if the catalytic converter may be clogged If you do need to replace the MAF sensor, we recommend using an original equipment OEM one from the manufacturer rather than buying an aftermarket part. Note: The use of a reusable oiled air filter could be a cause of this code, if it is over-oiled. Oil can transfer to the fine wire or film inside the MAF sensor and contaminate it. Use something such as MAF cleaner spray to clean the MAF in such situations.
