P0106 Saturn Code - Manifold Absolute Pressure Performance
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0106 Saturn Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM determines the MAP Sensor is stuck within the normal operating range. It accomplishes this by running 3 different models within the software to determine the values.
What are the Possible Causes of the DTC P0106 Saturn?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0106 Saturn?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0106 Saturn code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0106 Saturn Code
1. What does the OBDII code P0106 mean for a Saturn vehicle?
P0106 indicates a problem with the Manifold Absolute Pressure (MAP) sensor's performance, showing that its signal is out of the expected range for engine operation.
2. What are common symptoms of a P0106 code in a Saturn?
Symptoms include poor engine performance, rough idling, stalling, reduced fuel efficiency, difficulty starting, and an illuminated Check Engine Light.
3. What causes the P0106 code in a Saturn?
Common causes include a faulty MAP sensor, wiring or connector issues, vacuum leaks, clogged or dirty air filters, or problems with the engine control module (ECM).
4. Can a dirty air filter trigger a P0106 code in a Saturn?
Yes, a clogged or dirty air filter can restrict airflow and cause incorrect MAP sensor readings, leading to a P0106 code.
5. How do I diagnose a P0106 code in my Saturn?
Start by inspecting the MAP sensor, wiring, and connectors for damage. Check for vacuum leaks or clogged air filters, and use a scan tool to monitor MAP sensor readings.
6. Is a P0106 code safe to drive with on a Saturn?
Driving with a P0106 code is not recommended, as it can lead to reduced fuel efficiency, poor engine performance, and potential engine damage if the underlying issue is not resolved.
7. How do I fix a P0106 code on my Saturn?
Repairs may include replacing a faulty MAP sensor, cleaning or replacing the air filter, fixing vacuum leaks, repairing damaged wiring, or reprogramming the ECM if needed.
8. Can a vacuum leak cause a P0106 code on a Saturn?
Yes, a vacuum leak can disrupt engine pressure readings and cause the MAP sensor to perform outside its expected range, triggering the P0106 code.
9. How much does it cost to fix a P0106 code on a Saturn?
The cost depends on the root cause, ranging from $50 to $200 for a MAP sensor replacement or more if additional repairs, like fixing vacuum leaks, are required.
10. Can a faulty ECM cause a P0106 code in a Saturn?
While less common, a malfunctioning ECM can misinterpret MAP sensor data or fail to process the signal correctly, resulting in a P0106 code.
