Controlling engine emissions requires a lot of different components. Catalytic converters are part of your exhaust system, and are responsible for burning off harmful gases, or converting them into something harmless (like oxygen). Catalytic converters use precious metals like platinum,...

There is a label in the drivers door opening that specifies how much pressure should be in the tires. I'm guessing it should be around 34 psi.

Hi there: Typically a dashboard warning light is an indication that the ECU has detected a fault of some type of an electrical or mechanical component. If the electric power steering light is illuminated, it's likely that one of the...

Hi there. The catalytic converter on your Honda Accord has two oxygen sensors. One oxygen sensor is positioned in front of the catalytic converter and the other oxygen sensor is positioned in the rear. When the oxygen sensors have a...

Hi there. In most cases, a squeaking noise coming from a wheel is caused by worn out wheel bearings. This is common with a Porsche and many other European performance models around 50,000 miles. However, it could also be a...

The actual fuel pressure and volume should be measured. Be sure the gas is not older than three months. You do have an OBD-II diagnostic system, so check for diagnostic trouble codes and a real time scanner would help pinpoint...

The downstream oxygen sensor (post converter) monitors the efficiency of the catalytic converter. If there is no downstream sensor after the second converter then the P0420 code cannot arise from a fault there. Exhaust leaks have to repaired anyway, due...

Hi there. Usually white smoke coming from the exhaust pipe is caused by a mixture of engine oil and coolant. In most cases, this is caused by damage to the engine, like a blown head gasket or cracked engine block....

Below is a process to follow after reprogramming transmission module or disconnecting battery so the TCM can relearn shift points. If after following the below service then seek a mechanic like one from Your Mechanic to continue further diagnosis of...
