What Does P0129 Mean?
What Does P0129 Mean?
Barometric Pressure Too Low
OBD-II Code P0129 is defined as a Barometric Pressure Too Low. The engine control module (PCM) uses a Pressure sensor in the intake to determine airflow through the engine.
What does the code p0129 mean on an OBD II?
What Does Code P0129 Mean? When a P0129 code is stored in your OBD-II equipped vehicle, it means that the powertrain control module (PCM) has detected a low barometric pressure reading from the barometric pressure sensor (BPS) or the manifold air pressure sensor (MAP).
What does p0122 mean on a TPS sensor?
A P0122 code means that the the vehicle’s computer has detected that the TPS (throttle position sensor) “A” is reporting too low a voltage.
Where is the p0129 barometric pressure sensor located?
If the BPS input signal varies by more than a set limit, a P0129 will be stored. Other automakers choose to integrate the BPS with the MAP sensor. In this type of system the sensor is normally mounted directly to the engine intake manifold and sealed with some type of o-ring.

What are the symptoms of a p0129 OBD code?
Symptoms of a P0129 code may include: Excessively rich fuel delivery conditions. General lack of engine performance. Hesitation upon acceleration. Black smoke from exhaust. Diminished fuel efficiency.
When do I get a p0129 Mil code?
If the PCM detects a BPS input signal that varies from comparison data by more than the programmed limit, a P0129 will be stored and a MIL will possibly be illuminated. Symptoms of a P0129 code may include:
What does diagnostic trouble code ( DTC ) mean?
What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Dodge, Chrysler, Hyundai, Jeep, Mazda, etc.). Although generic, the specific repair steps may vary depending on make/model.
