This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Simply put, this means your car is adding more pollution into the air than it’s supposed to. SAVE MONEY and buy Motor Oils and Car Parts online - FREE SHIPPING! Most people replace parts that are not needed.

This code is ALMOST ALWAYS this issue. Replacing your catalytic converter is costly, so, knowing if a new catalytic converter is needed pays off. I wrote a much more detailed explanation of how an emission system works and what causes these codes.

Read this post and then refer to this more detailed post. Bank is the passenger side. The most common cause of this code is due to a faulty catalytic converter. Bad oxygen sensors are also a possibility but if this is the case an oxygen sensor code will usually accompany the catalytic converter code. Always diagnose and repair oxygen sensor codes before attempting to diagnose catalytic converter codes.

Truck (details in sig) threw a 4code the other day. It is part of the vehicle emissions system. Take the tune off and wait for the code to come back, then give it to the dealer. The Osensors readings while the car was operating seemed like they were good = there was a wave like graph generated from both pre-cat sensors and a level reading for both post-cat sensors.

There were times it was a bit jumpy, but overall they were good it seemed. They did clear the code and I drove And this website Technorati Twitter _____ Black KJ. I jiggled the wires on that sensor and the check engine light went off. The Check Engine Light has come on a couple of times since.

If none of these codes are present in step 1), go to next step. Check Rear HO2S Wiring Harness Turn ignition off. It might take a couple of days for the CEL to come back on and set the code.

Taking your car into a shop will cost you around $2depending on the car. There are pre-converters and then one on thestraight main pipe. Which one is failing to give this code ? Infiniti recommends premium unleaded for this vehicle. Try checking for exhaust leaks or changing the post Osensors before changing the cats. Normal wear on cats is more than 130K.

You have a few options here: 1. So, with the code scanner, I had codes. Cleared the computer and took the truck for a drive. Of course, the light came back on, but when I ran the scanner, it found codes. This is known as the downstream Osensor, they are the ones that throw this code.

OBS 73K miles The other day my truck started running like it was on four cylinders and the check engine light started flashing. CEL came on a couple of days ago. I believe the catalytic converter must be replace. The questions I have are: 1. PCM runs a test on the cat and if it fails it will set these codes. After some investigation I have a solution that can save everyone a lot of money.

UPDATE: Well, I have tried two more rounds of B-Chem-tool and my check engine light is still on. I have had the code reset several times, but the check engine light comes on within a day or two. When your vehicle generates those emission codes it simply means that the converter is not able to function properly.

Remember that the catalytic converter is at the very end of the emission diagnostic system, and a number of things can go wrong upstream of the converter that can cause. PO4(or PO430) MIL light illumination. Local Garage replaced one catalytic converter and said they installed a 69.

Next day check engine light came on again with same code.

Este código se establece cuando la ECU (Unidad de Control del Motor) detecta un rendimiento que está por debajo del nivel del TWC (Convertidor catalítico de vías). That is a picture of the PURGE VACUUM DIAGNOSTIC SWITCH. Daily driver and weekend wheeler (more like bi-annually these days). Heavily armore meticulously maintained. Theory of Operation The State of Change (SOC) catalyst monitor uses the signals from both the upstream and downstream Osensors to detect aging of the catalyst.

Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. Then the mechanic said that he had overlooked changing the two Osensors in bank and did so. Two sorry shops took you down the wrong road.

Just wanted to share a success story that may help others. Carl Stolz – Technical Sales Manager, DEC. Catalyst performance below threshold. First, if ANY other OBDII codes are present, address them. Listen man, this is a possible cheap fix.

First months, it came off and on, then after that, it stayed on for the next months solid. Well this just happened about hours ago well driving. What in the world does that really mean.
