Where are the O2 sensors located on a 2005 Jeep Grand Cherokee?
The front/upper upstream sensor (1/1) is located in the exhaust downpipe just before the front mini-catalytic convertor. The rear/lower downstream sensor (2/2) is located in the exhaust downpipe just after the rear mini-catalytic convertor, and before the main catalytic convertor.
Where is the O2 sensor located on a wrangler?
Simple, upstream means the O2 sensor is “upstream” of the catalytic convertors, meaning before the catalytic convertors.
Is the Jeep Wrangler TJ sensitive to oxygen?
Pay close attention to this one so you can do it once and do it right! The Jeep Wrangler TJ is extremely sensitive to all oxygen sensors other than NGK / NTK. Bosch O2 sensors and all the others (including the crappy Chinese brands you’ll buy at your local auto part store) are very well documented as not working properly with our TJs.
What are the sensor codes for a Jeep Wrangler?
I own a 2000 Wrangler 4.0L sport, and recently got the (OBDII) P0132 & P0138 codes which are High Voltage Output in sensors 1 & 2. I had to search this forum, as well as other sites to make sure I was investing my money the right way . Anywayz here’s the breakdown: 1. Got the codes P0132 & P0138. 2.
Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
Where is the downstream O2 sensor located?
The downstream oxygen sensor is located in the exhaust pipe after the catalytic converter. The role of the downstream oxygen sensor is to monitor the working and efficiency of the catalytic converter. There may be one or two oxygen sensors depending on the number of cylinders. The ECU compares the signal from upstream and downstream sensors.
Where is the Bank One O2 sensor?
Bank one is the engine cylinder bank near the engine firewall (see diagram). The bank one sensor one is the Oxygen sensor (O2) located in the exhaust pipe just of the engine cylinder bank at rear and before the Catalytic Converters .
Where is the rear O2 sensor located?
The rear oxygen sensor is located in the front section of the rear catalytic converter. On the 2.2L engine the front (A/F) oxygen sensor is located in the front section of the front catalytic converter. The rear oxygen sensor is located in the rear section of the rear catalytic converter.
Where does the oxygen sensor plug in?
O2 sensors look like a plug sticking out of the exhaust system. They are normally positioned either in the catalytic converter or before and after it (with two separate sensors). Unplug the electrical wiring from the sensor. Squeeze the release tab and pull the plug out from the sensor housing.
