2.1 v6 gives me strong pulls once a month when it is hot, gives them for a few seconds and removes, change lambda sensor (error P037) but have not removed the pulls and now I marked the P0333, what problem can my car? Thank you

 

I'll assume your first code should actually have been = p0337 = stored code P0337 (in the past) it was because the powertrain control module (PCM) had detected a low input voltage signal from the crankshaft position (CKP) sensor circuit.

P0333 = is the knock position sensor (a.k.a. CKP) bank 2 = usually best to replace both banks at the same. time. This code will usually send the car into restricted performance mode (bucking, hick-up, jerking) in other words "limp mode".

 

Good Morning
the error that gave me first is the P0037 and now I have the P0333
Attached screen of the before and after the pulls can come by the P0333?

As Dell said earlier, P0333 is the knock sensor, but I think you'll find there's only one, not one for each bank. By design, that fault will limit the engine speed below normal.

The other code, P0037, is for the lower of the two O2 sensors on the exhaust system on the firewall side of the engine.

A new knock sensor and a new O2 sensor should see you back to normal, assuming all the wiring and connections are good

 

about knock sensor #2 or bank 2. As said, there is only one knock sensor on the AJV6, but standard OBD II P codes for all cars give a placeholder in the P code list for 2 knock sensors as a lot of engines use two. The AJV6 engine management system is programmed to use bank 2 as the default reporting code for THE knock sensor.

The same engine in an S is configured with 2 sensors.

Thanks for catching that Astro.

 

This post by Patterson shares a clever location for the new knock sensor:
