after diagnosing the codes, i need help plz
today during my break i went out and meddled with my ecu, finally got it to work and found 4 codes, after diagnosing them i found them to be these 4..
1. intake air temp sensor
2. MAP/BARO SW Solenoid/Valve
3. Absolute Pressure Sensor
4. Revolution Sensor
but now that i have these i have exactly no clue on the first step to fixing them is, some help plz

benny year of your car would help a little. location of these parts vary slightly in the 4th gens.
i know the code 3. is an 0803 i get that one all the time i have a map sensor(aka boost sensor) that is on its way out.

0401
Diagnostic Trouble Code 0401 points to a problem with the Intake Air Temperature Sensor. The IATS is mounted in the engine air intake duct, downstream of the air cleaner filter. It detects intake air temperature and transmits a signal to the Engine Control Module. The sensor uses a thermistor, a resistor with a value which is inversely proportional to temperature. The IATS is not directly used to control the engine. It is used only for diagnostic purposes. Therefore the engine should start and run normally, even with the Malfunction Indicator Light on and DTC 0401 stored.
This malfunction is detected when ...
a) An excessively low or high voltage from the sensor is detected by the ECM.
b) The signal from the IATS is inconsistent with the signal received from the Engine Coolant Temperature Sensor.
Possible causes include ...
- Harness or connectors (The sensor circuit is open or shorted.)
- a faulty Intake Air Temperature Sensor
The IATS resistance values should be ...
- at 14 degrees F, 7.0-11.4 Kohms
- at 68 degrees F, 2.1-2.9 Kohms
- at 176 degrees F, 0.27-0.38 Kohms
For further information about the Intake Air Temperature Sensor please refer to the Chilton repair manual (page 4-16) or the Haynes repair manual (page 6-11).
