When backing up, my suburban stalled. I bought a pocket scan and the code came up P0332.? any ideas?

Definition of check engine code P0443:
Generic (Common for all car manufacturers):
Evaporative Emission System Purge Control Valve Circuit
Where do you get cam sensor from I wonder.

Purge valve stuck open and the engine will get incorrect mixture then stall.

Question edited for clarity. Your code is 'upper case 'P', zero, not lowercase nought 'o'.

And 'year make model' as the first 3 words in every question please.

Videos if it is a Chevy. What the code means lower down in second link

Did you get the AC plugs? or off brand? This sounds like a faulty plug issue

when you replace sensor trouble codes must be cleared out. or it will keep showing up, like yours

P0332 DTC Code - Knock Sensor 1 Circuit Low Input (Bank 2)
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged.

The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.

You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms.

Potential causes for a P0332 DTC include (but are not limited to):
The knock sensor is faulty and needs to be replaced
There is a wiring open/short/fault in the knock sensor circuit
The PCM/ECM has failed

check to make sure there is no vacuum going to the egr valve at idle if there is plug the line.

Thru all of the above, has the check engine light ever gone on? Even if it hasn't I'd have the engine codes checked w/ a scan tool, to see if there are any stored codes on the Suburbans computer. U can have it done for free at most parts stores, and they will give u info on what to do to correct any trouble codes that show up. Do the above, and after discussing any codes w/ parts store , if u need further help, let me know. Good Luck!

Scan tool readings on pre 96 (OBD 1) are not always helpful. What are the symptoms? No spark? Ignition module is common failed part. Parts stores can test these, but not always accurate. Worth a try, or just replace it.
