SOURCE: can a 2003 volkswagon jetta tdi run without a

Sure you can run without the converter... It may trigger your engine light to go on. Also, you're increasing your emissions and it's against Federal law to remove emission control equipment. If you're caught, the fine can be a hefty one. Also, your car won't pass an E-Test and at that point, they'll know the converter has been tampered with.

A converter will cost you $150 to $300 on average. Go with Bosal if you don't want to spend a lot of money

Seems problem exists more so from the recall to replace the so called Faulty Ignition coil. I had mine replaced by Recall Notice. I packed up the car and headed north for the weekend - 1st drive after coil replacement approx 190km - upon return for the weekend another approx 80 km the engine lite came on. Returned to my dealer here in Toronto and they assessed the Cat trouble. Researched Cat converters - Dudes and Dudettes. This Cat trouble is bogus- Cats should out last 2 car's unless your power is way down and you can't keep it running - and noticeable loss of power would ever a cat be required to be replaced. This is to get you to come in and spend your money with them. Car care has become another great business of scamming legally. You the ****** are always taken for non-required service. Research and you will always be ahead of their game. I'm also suffering this habit of engine lights coming on. I'm thinking of the investment to an ODT2 unit and keep it with me for such occasions to clear the codes and await it to return. Which I'd expect will be some time again. VW's are made for the autobaun - meaning hard driving. Don't let some whistle head talk you into spending more then you need. Cash flow management. Cheers.

My 2003 chevy impala just loses power while driving, it seems like its choking for a while then regains power again and runs normal


have car checked for a plugged catalytic converter by a reputable technician. A clogged catalytic converter results in a loss of power. The catalytic converter is made of an aluminum oxide honeycomb coated with platinum and palladium. These components react to remove CO and HC's from the exhaust stream. A two-way catalytic converter works by oxidizing CO (carbon monoxide) and HC (hydrocarbons "unburned fuel") to CO2 (carbon dioxide) and water. A three-way catalytic converter also removes NOx (oxides of nitrogen) from the exhaust. NOx is formed at high cylinder temperatures. The EGR system is responsible for inhibiting NOx.

I would like to know how many o2 sensors are in a 2003 jetta 1.8t gas.


If you can locate the catalytic converter the front O2 sensor , referred to as sensor 1 or S1 , is located in the inlet pipe for the catalytic converter , 6" to 12" upstream.
The rear sensor , referred to as sensor 2 or S2 , is located in the outlet pipe , 6" to 12" downstream.
The exact distance from the catalytic converter varies by engine type , i.e , 2.O liter ,1.8 Turbo

The check engine lamp on my vw jetta 3 is ''on'', i put a diagnostic reader on and it showed the following codes:P0422,P0411,P0300B,P0301B,P0302 and P00172B, what do they mean and how can i solve the...


P0422 - 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

Could someone tell me what the error codes P0141 P0036 on a 2003 Jetta means? thx


The error codes you have are for the O2 Sensors. There is one before and after the catalytic converter. It is usually the first O2 sensor that is the problem because the second sensor is used just to verify the converter is working. The O2 sensors are usually $60 to $130 dollars depending on the type your vehicle uses. they are located on the downpipe on the exhaust system and the other is locted after the catalytic converter on the exhaust system. The O2 sensor not working will cause you gas mileage to be reduced because the car's computer will run the fuel mixter rich.

Install heated oxygen sensor number 1 in volswagen jetta


Hi:
The Number 1 Heated Oxygen sensor is located in front of the catalytic converter. You would need to get the car up in the air, and then disconnect the electrical connector, and possibly need a special socket to remove the sensor. Also remember to purchase and use Oxygen sensor safe anti sieze compound on the threads of the new sensor, if you do this your self
