Diagnostic code error P0306 and P0420 on 2003 Pontiac Grand Am GT


this obd2 trouble code table can help you understand the meaning of code.
and for p040,you can try:

Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
Inspect the downstream heated oxygen sensor (HO2), replace if necessary
Replace the catalytic converter
for p0306, you can try
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

HOW WOULD I TELL THE DIFFEENCE BETWEEN A BAD INJECTOR AND A PLUGGED CAT


A bad injector would give the engine a cylinder misfire. You would have a check engine light with a P0300-P0306 code stored in the computer. A plugged cat would make the car feel like it has no horsepower and would set a check engine light with a P0420 code. Usally if you put your hand and feel the exhaust out the tail pipe a plugged cat you will feel little air comming out like if you just were breathing hot breath on your hand, where a good cat you will feel stronger air and slight pulsations in the exhaust.

Please explain hyundai terracan 2002 fault codes p1730 front speed sensor low input, p1732,p1734 low input,how to find problem, low range there is no opperation at all, cheers ,clive.ps in the model...


P1730 Front Speed Sensor - Low Input
P1732 Rear Speed Sensor - Low Input
P1734 Speed Sensor Reference - Low
These are all references to Electronic Stability Control or ABS systems. If there's no problem with wiring, then you could safely assume the speed sensors are bad.
