This summary uses the existing diagnostic information shown in full below.
The car's computer is getting a signal that the air pressure inside the engine is too high. It's like when you blow too much air into a balloon and it feels tight.
This code indicates that the signal voltage from the manifold absolute pressure (MAP) sensor is higher than expected by the engine control module (ECM).
The MAP sensor measures the pressure inside the intake manifold and sends this information to the ECM. A high circuit signal suggests that the sensor is reading a higher than normal pressure, which could be due to a sensor malfunction, wiring issue, or actual high pressure in the manifold.
• Check Engine Light is on
• Poor engine performance
• Increased fuel consumption
• Faulty MAP sensor
• Wiring issues or poor electrical connections
• Vacuum leaks in the intake manifold
MAP Sensor: Manifold Absolute Pressure Sensor, which measures the pressure inside the intake manifold.
ECM: Engine Control Module, the computer that manages engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the MAP sensor and its wiring for damage.
• Check for vacuum leaks in the intake manifold.
• Replace the MAP sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Fix any vacuum leaks in the intake manifold.
• OBD-II scanner
• Multimeter
• Vacuum gauge

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and clean the MAP sensor.
• Ensure all engine vacuum lines are secure and intact.
• Perform regular engine maintenance checks.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regular maintenance can prevent such issues.
Check with the vehicle manufacturer for sensor warranty coverage.
This code has been commonly associated with sensor failures and wiring issues in older vehicle models.
Moderate – It should be addressed soon to prevent further engine issues.
Driving with this code may lead to increased emissions and reduced engine performance.
• Engine at operating temperature
• Vehicle idling in neutral
The MAP sensor is typically located on the intake manifold or near the throttle body.
Q: Can I drive with a P119A code?
A: It's possible to drive short distances, but it's best to address the issue soon to avoid further damage.
Q: How do I reset the Check Engine Light after fixing the issue?
A: You can use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
Pro · Four-system diagnostics
A handheld scanner aimed at engine, transmission, ABS, and airbag diagnostic work.
Chassis and ABS faults usually need a scanner that can read brake-system data directly.
