The knock sensor is screwed in the engine block below the intake manifold, and the O2 sensor (Oxygen sensor) is in the exhaust system. Most cars have more than one oxygen sensor. The knock sensor detects "knock" or fuel detonation in the engine, that is fuel that starts to burn without spark, and at the wrong time. Fuel knock can be harmful to an engine. From what I can see on the internet, knock sensors are a common replacement item on Nissans, not sure if people are replacing them because they commonly go bad, or replace them blindly, just by seeing the code. The O2 sensors in your exhaust are what indicates to your engine computer how well it's doing a job of injecting the correct amount of fuel at the right time and what adjustments it needs to do. Fault codes in electronic control systems need to be interpreted... Lots of people just see the codes and replace the sensors related to the codes. This might fix the problem sometimes, but lots of times the codes can be attributed to something else... You might change both the sensors and cure the problem, but you might dump money into replacing these parts for nothing and the problem could lie somewhere else (fuel pressure regulator, ignition components, etc...) Also it depends if these codes were "active" (still happening at the time of connecting it to the machine) or "passive" (happened at some point but not happening at the time of connecting it to the diagnostics machine). If they're active they are a lot easier to diagnose and fix than if they are inactive. I know for a fact, working in the field, inactive codes are often next to impossible to repair in decent time.

1995 S-10 Blazer- service engine light is on?


Po172 refers to an oxygen sensor. But after you service the part you need to clear the code with an OBD II scanner. You can get a reliable inexpensive one at Harbor Freight. After you clear the code then you to start the car and drive it to see if the code comes back on. Also if you have a vacuum leak this can cause the system to run either rich or lean depending on circumstances.

First question is - is the check engine light on ?
If yes you should check it for codes next.
You may have to use a scanner to watch the O2 sensor to figure out if it is too lean or too rich. I would also check fuel pressure at the rail with a gauge to make sure pressure is normal. Could be a faulty fuel pressure regulator among other things.

Check your transmission output shaft speed sensor. First check that the connector is clean, free of corrosion, secured firmly and that wires have good insulation. If all looks well at this point then disconnect the speed sensor, remove it and clean its tip of any debris and see if this clears the DTC. If not change the sensor for a new one (less than $30). This should fix it.

Code 1346 on 2002 toyota sienna


P1346 is the code for:
VVT Sensor /Camshaft Position Sensor Circuit Range/ Performance Problem (Bank 1)
If the code came on just after the timing belt replacement more than likely the sensor was damged in some way during the work. The sensor is located in the same area the mechanic was working in while changeing the timing belt. You should have this checked right away. A faulty cam sensor can also lead to the vehicle not starting.
