P1108 SUZUKI Possible Causes
- Faulty Manifold Absolute Pressure (MAP) sensor
- Manifold Absolute Pressure (MAP) sensor harness is open or shorted
- Poor electrical connection in the Manifold Absolute Pressure (MAP) sensor circuit
How to Fix P1108 SUZUKI Code?
Start by checking the “Possible Causes” listed above. Visually inspect the corresponding wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
Illuminated engine light (or service engine soon warning light)
P1108 SUZUKI Meaning
The Manifold Absolute Pressure (MAP) sensor provides instant manifold pressure information to the engine’s Engine Control Module (ECM). The data is used to calculate air density and determine the engine’s mass air flow rate, which in turn determines the required fuel delivery for optimal combustion. A fuel-injected engine may also use a Mass Air Flow (MAF) sensor to detect intake air flow. A typical configuration uses one or the other, but rarely both. The MAP/BARO Switch solenoid valve switches the air flow passage based on the voltage signal sent by the ECM.
