As late model F430 fall out of the authorised dealer network more and more people are taking the preventative step of removing the small catalytic converters in the exhaust manifold. If the catalytic converter is not working correctly the oxygen sensor will set a code or if the vehicle is getting too much or not enough fuel the computer will also set a code.

If the computer says that the oxygen sensors are not ready this is due to the vehicle not being warm enough which it generally only takes 2 - 5 minutes for the exhaust to be fully warm up for the system to read.

There is also the possibility that the catalytic converters efficiency is compromised with oil deposits or other contamination or water from some bad gasoline or just plain gunk from the years of exhaust passing through it. It could be a faulty line of computer code that pulses an injector too long or it could be a stuck piston ring that allows oil to be sucked into the combustion chamber. Almost every part on the engine determines how long a catalytic converter will last.

All other indicators are in the ready mode. The smog guy California says that he can let another monito. Catalytic converter efficiency not ready secondary air system not ready evap emissions control system not ready oxygen sensors not ready EGR flow not ready.

Converter efficiency is. Two weeks ago I went to a California smog test station and they said my 5-speed 97 2wd 4Runner with 150k miles with original cats and oxygen sensors would fail because the catalytic converter monitor wasnt ready. Because of the way they are constructed using rare metals like platinum palladium and rhodium catalytic converters are expensive costing upwards of 1000 not inclusive of diagnosis and installation.

I have ABSOLUTELY NO idea what sensors monitor and report on this. Despite there being no apparent change in the engine ECU software during the production run it has become apparent that the catalytic converter monitoring was. I tried driving about 25 freeway miles without traffic in the following conditions.

4 drive cycles they remain not ready. Catalytic Converter Efficiency Not Ready. Diagnosing a plugged converter is fairly easy but diagnosing converter efficiency requires tapping into the OBD II system with a scan tool to check for codes and to compare the upstream and downstream O2 sensor readings.

Is it Smog TEST or Emission test time already. Converters typically fail one of two ways. This will surely make the vehicle fail.

Catalyst Monitor trick for older vehiclesTired old car with high miles and your catalyst CAT monitor is not ready INC. The catalytic converter uses precious metals and high heat to oxidize and reduce harmful emissions converting them into safer compounds like H2O CO2 nitrogen N2. The monitor compares the signals from the upstream and downstream oxygen sensors to monitor the operation of the catalytic converter.

However the Catalytic Converter Eff is also Not Ready and the Peoples Republic of Illinois only allow 1 not ready in order to pass. Other times the catalytic converters are not efficient enough to set the monitor to ready but at the same time not bad enough to set a trouble code. First 2 of 2 Go to page.

The catalyst efficiency monitor verifies the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within the predetermined values. All the above tips are moot and useless if you have already failed a test due to your catalytic converter being old. Catalyst Efficiency Monitor Not Ready The Catalyst Efficiency Monitor verifies the catalytic converter is operating at high enough efficiency to keep exhaust emissions within acceptable limits.

I found that there is an easy method to clean it out after which it registers good catalyst system efficiency again. They get too hot melt and plug up or the catalyst becomes contaminated and useless. I have a 2002 Acura RSXS in which the Not Ready is indicated for the catalytic converter.

Im going to show you a little tri.
