The P1108 code is a manufacturer-specific powertrain code related to fuel and air metering. In this case it means that the engine control module (ECM) has detected a fault with the barometric pressure (BARO) sensor signalling a higher than normal voltage signal.
How do I fix code P1106?
What repairs can fix the P1106 code?
- Repair damaged or defective electrical wiring and related components.
- Repair any airflow issues that may be occurring related to the engine.
- Clean and/or replace clogged filters.
- Repair any vacuum leaks.
- Clear clogged catalytic converter(s)
- Replace damaged or defective MAP sensor.
What is BARO on scanner?
The BARO sensor reads the barometric pressure. The PCM uses this information to make adjustments to fuel trim and engine timing.
What causes a P0108 code?
Code P0108 sets when the voltage to the PCM from the MAP/Baro Sensor Circuit stays above 4.5 volts for 10 seconds or more when the values from the Throttle Position, RPM and Oxygen sensors are changing. A vehicle with this code should be taken in to a repair shop for diagnosis.
What should my Baro sensor read?
With the engine not running and the key on, the MAP sensor should read around 28-inHg. When the engine is started and idling, the vacuum of the engine should reduce atmospheric barometric pressure by 20-inHg. The reading on the scan tool scan tool should be approximately 8- to 9-inHg.
What is Baro sensor range?
With the engine running at idle, the signal voltage should drop to around 1-2 Volts; when the engine is accelerated sharply, the signal should change to around 4-4.5 Volts. The barometric pressure sensor (BARO) measures the atmospheric pressure that varies with altitude.
What is a normal MAP sensor reading at idle?
With the ignition on, the MAP sensor output should be around 5 volts. Start the engine and check the reading; at idle, the MAP sensor should read 1 to 2 volts. This indicates the MAP sensor is responding to changes in vacuum. Digital MAP sensors are best tested with an oscilloscope.
How do I fix the code P0108?
Zitat von Youtube: Either next to or on the throttle body itself first carefully remove the map sensor from the engine inspect the map sensor for any damages. If the damages are found then replace the map sensor.
What are the symptoms of a failing MAP sensor?
Signs of a Broken MAP Sensor
- Poor Fuel Economy. If the ECM is reading low or no vacuum, it assumes the engine is at high load, so it dumps in more fuel and advances spark timing. …
- Lack of Power. …
- Failed Emissions Inspection. …
- Rough Idle. …
- Hard Starting. …
- Hesitation or Stalling. …
- Check Engine Light.
