What Does code po129 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. If the PCM detects the signal is too low, it will set code P0129.
What Does MAP sensor do?
MAP Sensors The sensor provides instant manifold pressure information to the engine’s electronic control unit. The data is used to calculate air density and determine the engine’s air mass flow rate, which in turn determines the required fuel delivery for perfect combustion.
How to know if your car has code p0129?
What are the symptoms of code P0129 ? 1 Hesitation upon acceleration. 2 Diminished fuel efficiency. 3 General lack of engine performance. 4 Black smoke from exhaust. 5 Excessively rich fuel delivery conditions.
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:
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 does trouble code p0128 mean on a car?
What Is Trouble Code P0128? This generic trouble code can affect most makes and models of vehicles. The code is signaled when your powertrain control module detects an unusual temperature reading while your engine is running. Typically, it’s signaled when your thermostat isn’t reading any temperature or is reading an incorrect temperature.
