Hi, befor anyone flames me, yes I did check the ECU descriptions for codes and did a seach.

I got a code 0803 (Absolute Pressure Sensor, but it is not in the description.

Can someone poste feedback on this please!?
What is it? where is it? How to fix it?

thank you

 

If I'm right, it'll be in the intake, just kinda shoved in a rubber grommet on the side below the filter box (atleast on my '97). Don't know how to fix it. I'd check the connection, though.

 

From Chilton manual - The absolute pressure sensor is connected to the MAP/BARO switch solenoid valve by a hose. The sensor detects ambient barometric pressure and intake manifold pressure, and sends a voltage signal to the ECM. As pressure increases, the voltage rises. The absolute pressure sensor is not used to control the engine system. It is only used for on-board diagnosis.



Testing
1. Remove sensor with its electrical harness connected.
2. Disconnect the vacuum hose from the sensor.
3. Turn the ignition swithc "ON".
4. Backprobe the sensor connector and check output voltage, from the white wire and ground.
5. The voltage should be 3.2-4.8 volts.
6. Connect a hand powered vacuum pump and apply a vacuum of 7.87in.Hg(26.7kPa).
7. Voltage should be 1.0-1.4 volts lower than the value in step 5.
8. If voltage is not within specification or does not respond as specified, check the power and ground circuits.
9. If the power and ground circuits are okay, the sensor may be faulty.

 

clee, maybe you could add this to the dct codes sticky?

 

Looks like I got it fixed, it seems the sensor came off a little.

Thanks to all for the input

 

I'm getting this same code. Has anyone else figured out how to fix this?

 

I must be the only one here who can type "0803" as a search string and come up with results.
