WIRING DIAGRAM

CIRCUIT DESCRIPTION
This sensor senses pressure change in the intake manifold and converts it into voltage change. It consists of a semi-conductor type pressure converting element which converts a pressure change into an electrical change and an integrated circuit which amplifies and corrects the electric change. The ECM sends a 5-volt reference voltage to the pressure sensor. As the manifold pressure changes, the electrical resistance of the sensor also changes. By monitoring the sensor output voltage, ECM knows the manifold pressure (intake air volume). ECM uses the voltage signal from the pressure sensor as one of the signals to control various devices.





DETECTING CONDITION AND POSSIBLE CAUSE

NOTE:
- It is possible that filter in MAP sensor is clogged by freezing. If it is suspected, leave it at room temperature (20°C, 68°F) for a while and proceed to the following inspection.
- Note that barometric pressure varies depending on weather conditions as well as altitude. Take that into consideration when inspecting.

DTC CONFIRMATION PROCEDURE
1. Turn ignition switch OFF. Clear DTC with ignition switch ON, check vehicle and environmental condition for:
- Indication of fuel level meter in combination meter: 1/4 or more
- Altitude (barometric pressure): 24OOm, 8OOOft or less (560mmHg, 75kPa or more)
- Ambient temp.: -10°C, 14°F or higher
- Intake air temp: 50°C, 122°F or lower
2. Start engine and keep it at idle for 2min.
3. Increase engine speed to 4000r/min and release accelerator pedal so that engine is in fuel cut condition.
4. Check DTC in "DTC" mode and pending DTC in "ON BOARD TEST" or "PENDING DTC" mode.
