What this code means

The PCM detected intermittent high voltage spikes from the Manifold Absolute Pressure sensor circuit. Unlike a steady high voltage (P0108), this code indicates a sporadic connection issue.

Symptoms

• Check Engine Light (intermittent)
• Intermittent rough running
• Hesitation during acceleration
• Poor fuel economy

Common causes

• Loose or corroded MAP sensor connector
• Intermittent wiring fault
• Faulty MAP sensor
• Damaged sensor ground circuit

Diagnostic steps

1. Wiggle test MAP sensor connector while monitoring voltage
2. Inspect wiring for chafing or damage
3. Test MAP sensor output across range
4. Check sensor ground circuit

Repair notes

Clean and reseat MAP sensor connector. Repair any damaged wiring. Replace MAP sensor if faulty.
