Air pressure sensor fault.
In modern engines the engine control module ecm measures or calculates air flow via either a mass air flow maf or manifold absolute pressure map sensor.
When a tire pressure sensor detects a problem with tire pressure it will send a signal to the car s computer which will then illuminate a light on the dash.
Turbocharged engines may use both but naturally aspirated engines typically use one or the other.
If you take your vehicle to your dealership or a dealer recommended repair shop they will likely be able to fix it in minutes with a scan tool.
The error code may tell you that the air pressure in the tires is too low or too high or the tire pressure sensor is defective.
Itpms do not use physical pressure sensors but monitor several wheel rotation speeds and other signs outside of the vehicle s tires to measure air pressures.
Ensure you also test the emergency tire as the most automobile has a force sensor in the spare tire which is habitually disregarded.
If the map sensor is failing or broken the ecm and thus the engine can t function properly.
Have you seen the message below on your autopilot v2 controller.
In these cases the sensor will need to be recalibrated or replaced.
Please contact customer service as soon as possible to resolve the issue.
Remember you are setting the sensors back to zero so all tires must be properly inflated otherwise the sensors will not be calibrated properly and their readings will be incorrect.
Itpms can not display or measure pressure values precisely they are relative by nature and need to be reset when checking tires and adjusting all pressure correctly.
The system will only operate in manual mode as the system uses pressure values to automatically make adjustments.
The fastest and simplest way to fix this fault is to check the pressure of all the tires using a quality air pressure test.
When this warning lamp illuminates on your instrument panel at least one of your tires is 25 percent below its correct pressure.
Both sensors illuminate the dash light when the pressure reading is lower than it s supposed to be alerting the driver to a tire with low air pressure.
What does a tire pressure sensor fault message look like.
You are seeing this message due to a failed pressure sensor.
If your car uses a battery to power the sensor be sure that it is not dead.
Additionally the air pressure gauge may be miscalibrated or the battery that powers the sensor may have died.
The position of the sensor is exactly within the speed sensors and braking systems.
