what engine? 4 wheel drive? Is this an OBDII code?

that means oxygen sensor bank 2 sensor 1 is running lean, I'll check for vacuum leaks around the intake manifold, if no could be just a faulty oxygen sensor

A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. this may help you. PO1131 PO1151 LEAN EXHAUST PO1131 PO1151 LEAN EXHAUST

the engine block indicator might be the computer check engine lamp. go to the local parts supply store that offer to plug into the computer to extract engine trouble codes. wright down all trouble codes. the trouble codes is only a guide for further trouble shooting.

Code 22 is the Water Temperature Circuit Open or Shorted.

Could be a bad mass air flow sensor. with the engine off unplug the sensor then test drive with sensor unplugged.(you can do this with almost all the sensors on this vehicle). It will replace the sensor data with a default parameter. If problem persists check fuel pressure.

The are many things that can cause your "check engine" light to stay on. One possibility is that although you have fixed the trouble code for your crankshaft position sensor, the code has not been erased from the computer's memory. Another possibility is that you have another issue going on that is causing a new trouble code to come up. You're going to need to have your car hooked up to a ODB-2 engine code reader to see what the issue is. These code readers are available for purchase at any auto parts store. In addition, many of your local auto parts stores will check trouble codes as a free service to customer. If not, many parts retailers offer the option to rent one of these code readers. Which ever way you decide to go, run a full engine/emissions trouble code check. If the only code that comes up is the code that came up previous to fixing your positioning sensor, then all you need to do is erase the trouble code from the computer's memory. (Most code readers have the option to erase trouble codes, but if you're going to rent or buy one, I would suggest that you check to make sure that the code reader that you're getting is capable of erasing trouble codes as some code readers only indicate the codes and will not remove them from your computer's memory.) If your trouble code scan reveals other codes, then you'll have to fix and erase them as they arise.

FYI- In my experience, I've noticed that 95% of the time that a check engine light/trouble code arises that it is usually an emissions problem (oxygen sensors, mass air-flow units, MAP sensors, etc.). However, General Motors products are notorious for getting trouble codes for having loose battery/ground connections and for having worn-out fuel caps. With any GM vehicle, I always check these two things first to try to save me from having to look further than I need to.

Hope this helps! I'm sure once you've scanned your cars computer and erased any existing trouble codes, that you'll stop being annoyed by your check engine light, as I know how bothersome it can be. Have a great day!
