Is bank 1 left or right?
Since Bank 1 is the rear one toward the firewall and has the sensors labeled RH it must be considered the right side of the engine. Conversely Bank 2 is toward the radiator, the front of the vehicle, and has the sensors labeled LH, that makes it the left side of the engine.
How many catalytic converters does a 2006 Scion tC?
The tC has 2 catalytic converters!
How many o2 sensors does a Scion tC have?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
Which 02 sensor is bank 2 sensor 2?
Bank 2 Sensor 2 = This O2 sensor is located right after the catalytic converter, on the side with the Cylinder #2 that is Bank 2.
Does 2006 Scion tC have catalytic converter?
Your Scion tC leaves the factory with a catalytic converter. It can run into problems over the normal life of the vehicle, and is often accompanied by OBDII code P0420.
How much does it cost to replace a catalytic converter on a Scion tC?
Scion tC Exhaust Manifold Replacement Cost Estimate. The average cost for a Scion tC exhaust manifold replacement is between $891 and $931. Labor costs are estimated between $104 and $132 while parts are priced between $786 and $800.
What happens when the O2 sensor goes lean?
When the computer receives a rich signal (high voltage) from the O2 sensor, it leans the fuel mixture to reduce the sensor’s reading. When the O2 sensor reading goes lean (low voltage), the computer reverses again making the fuel mixture go rich.
How many O2 sensors does a V8 engine need?
A second oxygen sensor is now used downstream of the catalytic converter to monitor the converter’s operating efficiency. On V6 or V8 engines with dual exhausts, this means up to four O2 sensors (one for each cylinder bank and one after each converter) may be used.
How does the OBD II system monitor emissions?
The OBD II system is designed to monitor the emissions performance of the engine. This includes keeping an eye on anything that might cause emissions to increase. The OBD II system compares the oxygen level readings of the O2 sensors before and after the converter to see if the converter is reducing the pollutants in the exhaust.
How to check and replace an oxygen sensor ( air )?
A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor. Nice O2 Sensor Socket Kit: http://www.amazon.com/gp/product/B005…
