Is the bank 1 sensor 1 upstream or downstream?
Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.
Is bank 1 the upstream sensor?
As far as oxygen sensor location goes, things are quite simple: Sensor 1 is the upstream oxygen sensor. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor.
Is bank 1 O2 sensor upstream?
The front oxygen sensor before the catalytic converter is usually called ‘upstream’ or Sensor 1. Therefore, in an in-line 4-cylinder engine, the term “Bank 1, Sensor 1” simply refers to the front oxygen sensor. “Bank 1, Sensor 2” is the rear oxygen sensor.
Which side of a Ford engine is Bank 1?
Bank 1 is the right side of the truck.
What’s the difference between upstream and downstream sensor?
“Upstream” refers to an oxygen sensor between the engine and the catalytic converter. “Downstream” refers to a sensor after the converter, also known sometimes as a “catalyst monitor sensor”. Bank 1 sensor 1 would be the upstream, bank 1 sensor 2 would be the downstream.
Which is p2238 sensor positive current control circuit low bank 1?
So the codes that ive been getting is p2238 (current control circuit low bank 1 sensor 1) and p2241 (pumping current circuit low (for a/f sonsor) bank 2 sensor 1) and so ive replaced the o2 sensors like this wiki said and there doesnt seem to be anything wrong with the electrical and the engine runs…
What is the trouble code for bank 1, sensor 1?
So you’re cruising along on a sunny day and all of the sudden that little yellow engine light pops up on your instrument cluster. You didn’t notice anything funny going on, so you go home and pull out your code reader, and you’re greeted with a trouble code: P0130 Heated Oxygen Sensor Bank 1, Sensor 1 Circuit Malfunction.
What are Bank 1 and 2 oxygen sensors?
Bank 1 sensor 1 would be the upstream, bank 1 sensor 2 would be the downstream. THANK YOU!!!! I am a computer repair person, but I love doing my own work on my car!!
