We had our car checked for a check engine light that goes on while driving and stays on then is not on when you restart the car. The codes they gave us were 212,332,542,543,116. The 332 is the egr valve not opening in which we had a feeling about, could this cause the other fault codes? The problem is we dont have 200.00 to buy one of those readers but dont want to buy parts that it doesnt need please help? Thank You

Hello,

Below is a no cost way to pull codes.....

To extract DTCs from the computer for diagnostic purposes, the Self Test connector is used.

1.Start engine and bring to normal operating temperature. If engine will not start or stalls after starting, proceed with next step.
2.Turn the key "OFF", then wait ten seconds.
3.Activate the self test by grounding the Self-Test Input (STI) connector.
4.Turn the ignition key "ON".
5.Record all codes received.
6.Turn ignition "OFF".

To answer your question No the EGR problem will not cause to other codes. The 542 & 543 codes have to do with the fuel pump circuit.... which could be the PCM....
542 - Fuel pump circuit open, EEC processor to motor ground.
543 - Fuel pump circuit open, battery to EEC processor.

116 - ECT(Engine Coolant Temperature) sensor is out of Self-Test.
212 - Loss of tachometer/IDM input. could be a number of things... Control Module, Coil Pack, Plugs and/or Wires, or Crank Shaft Position Sensor
332 - Insufficient EGR flow - could be Vacuum leak or Bad EGR Sensor
