Are all oxygen sensors the same thread?
They are physically and functionally identical and, wire permitting, can be interchanged with one another or with any “universal” 4-wire sensor of the type commonly sold at auto parts stores. The thread for all O2 sensors is 18 x 1.5mm.
What thread are oxygen sensors?
The OEMTOOLS Oxygen Sensor Thread Chaser is ideal for use with 3/4″ hex sockets or 3/8″ square drive. Includes sizes M18 x 1.5. It also works with M18 x 1.5 spark plug threads.
What size is oxygen sensor?
Registered. 7/8″ (22mm). Many times the O2 sensor will be bound pretty tightly, an open end wrench will most likely round off the hex. Get an O2 sensor socket, or you can get a regular deep 7/8″ socket, cut the wires to the old O2 sensor, and take it off with the regular socket.
What kind of oxygen sensor does Bosch use?
Bosch invented the automotive oxygen sensor, which is also referred to as an O2 sensor or lambda sensor. Our Premium Oxygen Sensors are thimble and planar switching sensors that are designed to meet or exceed OE specifications.
How does a wideband O2 sensor work?
Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel).
When do I get an oxygen sensor code?
The diagnostic strategies for wideband O2 sensors vary from one vehicle manufacturer to another but, as a rule, you’ll get an oxygen sensor code if the sensor reads out of its normal range, if the readings don’t make sense to the computer (should indicate lean when lean conditions exist, etc.) or if the heater circuit fails.
What should the resistance of the oxygen sensor be?
If the oxygen sensor calibration resistor value is found to be correct, measure the resistance value of the engine wiring harness (oxygen sensor and vehicle battery disconnected) between terminals 6 and 2. It should be approximately 62 Ω (Fig 8).
What should resistance be for Bosch oxygen sensor?
Check for short circuit between pins 3 and 4 and the outer metal casing of the oxygen sensor (Chassis ground) > 1 MΩ. If a resistance value lower than 1 MΩ is obtained, replace the oxygen sensor.
How does the Bosch wideband oxygen sensor work?
Bosch Wideband Oxygen Sensors Precisely Measure Air/Fuel Ratios. rich (too much fuel). To compensate, the computer adjusts the fuel mixture by adding more fuel when the mixture is lean, or using less fuel when it is rich. That’s the basic feedback fuel control loop in a nutshell.
How does the Bosch LSU 4 oxygen sensor work?
The Bosch LSU 4 wideband oxygen sensor is a 5-wire sensor that reads oxygen in much the same way as a traditional oxygen sensor. but it uses the latest “planar” construction with a special two-part sensing element to measure how much oxygen is in the exhaust.
Can a wideband O2 sensor be fooled?
One thing to keep in mind about wideband O2 sensors is that they can be fooled in the same way as a conventional oxygen sensor by air leaks between the exhaust manifold and head, and by misfires that allow unburned oxygen to pass through into the exhaust.
