OBD-II Code
P0332
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$150–$900
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0332 means the Knock Sensor 2 circuit on Bank 2 is reading low — the signal voltage from the bank-2 piezo crystal is pinned below the PCM's minimum threshold (typically under 0.1 V AC baseline or completely absent).
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

This is a circuit-low code
open signal wire, dead crystal, lost ground reference, or shorted-to-ground harness. Cheapest-first ladder: scan live data and look at the bank-2 knock counter (should accumulate 50 to 200 counts under hard acceleration on a healthy system; pinned at 0 means no signal reaching the PCM). Backprobe the bank-2 knock sensor signal wire at the PCM connector with a DMM set to AC volts — should read 0.5 to 1.5 V AC at idle with peaks during throttle blips. A reading under 0.05 V AC means the signal is dead at the PCM. Resistance-check the sensor itself: most knock sensors read 500 kohm to 5 megohm across terminals; below 100 kohm or fully open means the crystal is bad. Continuity-check the signal wire from sensor connector to PCM connector — should be under 1 ohm. Verify the sensor ground (typically a dedicated shielded ground at the PCM) has continuity to PCM ground under 0.1 ohm. Expensive misdiagnosis caveat: on GM LSx V8s, P0332 (bank 2 = passenger side on most longitudinal applications) requires intake manifold removal to access the sensor itself, but the harness pigtail at the under-intake connector is the failure point 80% of the time — pop the intake far enough to inspect and reseat the connector before ordering a new sensor that costs $40-$80 but takes $400 in labor to replace.
Vehicle-specific patterns1999-2013 GM LSx V8 5.3/6.0/6.2L (Silverado, Tahoe, Suburban, Yukon, Escalade, Camaro, Corvette) is the most common P0332 vehicle — bank 2 knock sens…
- 1999-2013GM LSx V8 5.3/6.0/6.2L (Silverado, Tahoe, Suburban, Yukon, Escalade, Camaro, Corvette) is the most common P0332 vehicle — bank 2 knock sensor sits in the lifter valley under the intake plenum and the harness pigtail corrodes from coolant weep past the intake gaskets; GM-style pigtail repair kit fixes most cases.
- 2004-2010Ford 4.6/5.4L Triton (F-150, Expedition, Mustang GT) throws P0332 from the bank-2 (passenger side) rear-of-head sensor wiring being baked by exhaust heat.
- 2007-2015Toyota 2GR-FE 3.5L V6 (Camry V6, Avalon, RAV4 V6, Sienna, Lexus ES350/RX350) throws P0332 from valley-buried sensor failure requiring intake plenum removal (6-8 hours labor).
- 2005-2012Nissan VQ35DE (350Z, Altima, Maxima, Murano) throws P0332 from corroded bank-2 sensor connector at the intake valley.
