Default Check Engine

Hello folks! Our Pt 2003 has its check engine light on so I took it to a local auto parts store and connected their machine, the guy said it the Oxygen sensor but it doesn't say which one, I'm planning on just changing both but my question is, is it hard to do? I'm not really well verse with cars but if its just a plug and play kinda thing i can do that ( I think?) is there any Schematics I can download??thanks in advance and keep on Cruzin'!!

P0456 Evaporative Emissions System - Small May be your gas cap, not on tight (3 clicks) or worn out and you need a new one.
=============================================

From PT Do-It-Yourself.net;

P0442-Evap System Medium Leak

A 0.040 leak has been detected in the evaporative system

When Monitored: Engine Running. Cold start test. Fuel Level greater than 12%. Ambient temperature between 4C and 32C (39F and 89F) Close Loop fuel system. Test runs when small leak test is maturing.

Set Condition: The PCM activates the EVAP Purge Solenoid to pull the EVAP system into a vacuum to close the NVLD switch. Once the NVLD switch is closed, the PCM turns the EVAP Purge solenoid off to seal the EVAP system. If the NVLD switch reopens before the calibrated amount of time for a Medium leak an error is detected. Two Trip Fault.

Possible causes include:

1.Intermittent Condition
2. Visual and Physical Inspection
3. Evaporative Emission Leak Detection
4. Evap Purge Solenoid Operation
5. NVLD Switch Operation


Specialized equipment is necessary to run the majority of tests, however you can conduct a Visual and Physical Inspection of the entire Evaporative Emission system.

Check for the follow conditions:

1. Holes or cracks.
2. Loose seal points.
3. Evidence of damaged components.
4. Incorrect routing of hoses and tubes.
5. Fuel Cap gasket seal. (A loose gas cap can cause this DTC to set. Make sure gas cap is tight and in good condition. Ensure the gas cap meets OEM specifications.)

====================================

The P0522 DTC is: Oil Pressure Sensor Low - Oil pressure sensor input below acceptable voltage.

Lots of owners get a bad Oil Pressure Sensor located on the back side of the engine as you stand at the front of the car.



-----------------------------------------------

None of these have anything to do with the 02 sensors. They have their own particular fault code.

The check engine light goes off if the problem is no longer present.
You can wait for it to reappear before you do anything.

When were wires and plugs last done?
Get a good brand of wires (stock ones are crap) - the stock champion plugs are fine - gap at 0.040.
If you haven't ever changed the air filter, that's a good idea, too.
