What Does the P0108 Code Mean? Diagnostic trouble code (DTC) P0108 code stands for “Manifold Absolute Pressure/Barometric Pressure High.” It is triggered by the ECM when it receives a signal from the MAP/BARO sensor circuit that is above the normal range.

What causes MAP sensor code?
A normal MAP sensor should read the manifold pressure as 1 to 4.5 volts. When this ratio is off, it can lead to misfires in the engine. The manifold pressure naturally changes based on the throttle position, but when it fluctuates dramatically, the P0106 code is triggered.
What could cause a MAP sensor code?
The source of the problem is that the MAP sensor range voltage output is incorrect and out of the programmed input required by the ECU. The most common problem is an air intake system vacuum or intake hose being loose, cracked, or missing it's plastic fittings and clamps.

What are the signs of a bad 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.
What causes low voltage on MAP sensor?
Here are the common reasons why your MAP sensor is sending too low of a voltage to the PCM: Faulty MAP sensor. Circuit issues, such as damaged wires or poor connections. Low engine vacuum.

What causes MAP sensor failure?
MAP sensors fail by getting clogged, contaminated, or damaged. Sometimes, engine heat “overcooks” the MAP sensor's electronics or cracks vacuum lines.
What would happen if the MAP sensor has low signal?
Look for these warning signs: Rich air-fuel ratio: Look for rough idle, poor fuel economy, slow acceleration and a strong smell of gasoline (especially at idle) Lean air-fuel ratio: Look for surging, stalling, lack of power, hesitation on acceleration, backfiring through the intake, and overheating.
