Just about any sight you search is going to ask for a year make model and engine. If you google search "04 pt cruiser converter" you will see plenty of option. I will warn you that buying an inferior converter will leave you with more problems. Buy one from a reputable manufacturer. Direct fit after market cats will give you the easiest installation. That actual o.e. part from the dealer will be best for the vehicle. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

There is but one source for the catlytic converter for your car, that is your local dealers parts dept. Aftermarket cats will not work, they will cause the check engine light to come and set code P0420.

7e8 engine code


Catalyst System Efficiency Below Threshold (Bank 1) What does that mean?



The catalytic converter is a part of the exhaust system that looks kind of like a muffler, although it\'s job is very different from that of a muffler. A catalytic converter\'s job is to reduce emmissions from the exhaust. The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 (or in your case, a 7e8 code) code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). Catalytic converters are not normally a "wear" type item, that is they are not deisgned to wear out and need replacement. If they have failed, it is likely due to something else that caused it to fail. Symptoms The main symptom to the driver is the illumination of the MIL (malfunction indicator lamp). You will likely not notice any drivability problems, although there may be symptoms. For example, if the substance inside the catalytic converter is broken or failed, it may be restricting the exhaust which will result in a feeling of reduced power output from the vehicle. Causes A code P0420 may mean that one or more of the following has happened: Leaded fuel was used where unleaded was called for A damaged or failed oxygen sensor (HO2S) Downstream oxygen sensor (HO2S) wiring damaged or connected improperly The engine coolant temperature sensor is not working properly Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe Retarded spark timing The oxygen sensors in front and behind the converter are reporting too similar of readings Leaking fuel injector or high fuel pressure Cylinder misfire Oil contamination Possible Solutions Some suggested steps for troubleshooting a P0420 error code include: 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 (HO2S), replace if necessary Replace the catalytic converter Overall probably the biggest mistake vehicles owners make when they have a P0420 code is to simply replace an oxygen sensor (H02S). It is important to do proper diagnosis so you\'re not wasting money replacing parts unnecessarily. We strongly recommend that if you need to replace the catalytic converter that you replace it with an OEM unit. Second choice would be a high-quality replacement part. There are many stories in our forums where folks replaced the cat with a cheaper aftermarket one only to have the code return shortly thereafter. One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it\'s out of it\'s bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It\'s worth checking into.

I replaced the stock catalytic converter on my 2004 Audi A4 1.8T about 3000 miles ago with a direct fit model from MagnaFlow because my mechanic said the original unit had failed and I didn't want to spend...

I ran an engine analyst and got codes P0446 twice and code P0431 once. what does this mean.


P0431 Warm up catalytic converter, bank 2 - efficiency below threshold
Possible causes: Catalytic converter, wiring, HO2S 2

Usually caused by worn out catalytic converter, but always check fuel pressure regulator for proper operation before replacing a converter.


P0446 Evaporative emission (EVAP) system, vent control -circuit malfunction
Possible causes: Wiring, EVAP canister purge valve, ECM

May be caused by a loose or disconnected wire to the vent valve or possibly a bad valve solenoid

If you would like part locations, troubleshooting or replacement procedures, please let me know.

2004 Dodge Ram P0420 code. What could be causing this? My emissions are clean (all were within limits), and I just replaced all 4 oxygen sensors


This code is set when the catalytic converters are operating below tolerable efficiency limits. Basically, your catalytic converters are bad and are in need of replacement. You can have bad converters and still pass emissions, but your computer uses the oxygen sensors to determine how well they are working. If the readings are out of a set tolerance, the check engine light will illuminate and DTC P0420 will set. Clearing the code will turn the light out temporarily, but the next time the test is run, the light will come on again.
Hope this helps.

P0422 Buick - Catalyst below threshold.

Catalytic converter is clogged or out of medium.

Replace it.


ACTUAL DIAGNOSTIC:

Fault Code Definition
Code P0422 indicates that the Bank 1 Main Catalytic Converter's emissions efficiency has fallen below the minimum allowable limit. This threshold is tracked by a Catalyst Monitoring Oxygen Sensor located on or near the outlet of the Catalytic Converter.

Symptoms

* Check Engine Light will illuminate
* In many cases, no abnormal symptoms may be noticed

Common Problems That Trigger the P0422 Code

* Defective Catalytic Converter
* Engine misfires have damaged the Catalytic Converter
* Internal engine damage resulting in high oil consumption and/or a leaking Head gasket has damaged the Catalytic Converter

Common Misdiagnoses

* Oxygen Sensors are replaced when the real problem is a damaged Catalyst
* Catalyst is replaced when the real problem is internal engine damage, which is producing elevated emissions levels
* Catalyst is replaced when a misfiring engine is the real problem

2004 Dodge Stratus Sedan. engine light stays on,


Take the vehicle to any auto parts store that offers to read the fault codes with a scanner for free and find out what that code is. If it shows Upstream or Downstream O2 sensor replace the O2 Sensor. There is a catch, dodge had an issue in the 2000 - 2004. The ECM will show a fault code that indicates the Catalytic converter is faulty. This is actually a faulty Downstream O2 Sensor. If you get a Catalytic converter fault code replace the O2 sensor first if you still have the problem then replace the converter.
