Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit Description
Manifold Absolute Pressure (MAP) sensor responds to changes in intake manifold pressure (vacuum). PCM applies 5 volts to MAP sensor. Changes in pressure, resulting from engine load and RPM, are converted into voltage input monitored by PCM. A low voltage reading at PCM indicates low manifold pressure, and a high voltage at PCM indicates high manifold pressure. DTC P0106 will set when voltage input at PCM is high with throttle closed, or voltage is low with TP sensor voltage greater than one volt.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
