Can a catalytic converter cause turbo problems?
2) Catalytic converter An overly-blocked catalytic convertor will slow down the turbocharger’s ability to “breathe”. Once the intake system fails to deliver adequate air to the engine, it may lead to higher exhaust gas temperatures and possible turbo / engine failure.
Does a turbo need a catalytic converter?
Turbo charged cars and trucks benefit from that extra exhaust flow that a turbo back exhaust system provides. We know that most people, when going full turbo back exhaust, will want to do so without the catalytic converters installed.
Can a bad EGR valve cause a catalytic converter code?
Because without proper EGR, combustion temperatures run too high. That not only increases NOx emissions, but also overheats the catalytic converter, causing damage to the ceramic brick. A new EGR valve costs about $100. As I said earlier, excess oxygen and fuel cause a catalytic converter to overheat and fail.
What happens if you put a turbo on your exhaust?
As the turbos start spinning, they heat up, especially on the exhaust side, Haynes explains. This heats up the incoming air, making it less dense and oxygen-rich, which cuts into power output. That’s why turbocharged engines have intercoolers—to cool the air after the turbo compresses it.
How can I make my turbo more powerful?
Pimp your turbo – 5 easy ways to maximise the power and performance of your turbocharged car
- Replacing the air filter. One of the easiest (and cheapest!)
- Colder air.
- ECU remapping.
- Exhaust.
- Upgrading the intercooler.
How does the rear oxygen sensor work on a catalytic converter?
The rear oxygen sensor (the one behind the converter) monitors how much oxygen is coming out of the converter at any time. A healthy converter will use a lot of oxygen, and so the rear oxygen sensor will see that there is little oxygen coming out of the back of the converter.
What happens if you replace the catalytic converter?
If you spend $900 or more to replace the catalytic converter, you may discover the check engine light coming on again later. Some mechanics will tell you to try replacing the oxygen sensors first, to see if that solves the problem. There are two of them, one before and one after the catalytic converter.
Can a check engine light be used on a catalytic converter?
If you have a check engine light, then this will illuminate on your heads-up display. Although you can get around this issue on some vehicles by fitting a spacer on your downstream O2 sensor (the lambda sensor), there is a risk that normal functionality does not return.
Can a car have two catalytic converters and four sensors?
Let’s say you have a car with two converters and four sensors. If only one of the converters has failed, you can sometimes connect both rear sensor signal wires together and the average of the two makes both look good in the eyes of the PCM (Powertrain Control Module).
