Service engine light on. Problem identified as P0332 Knock Sensor 2 Circut Low Input Bank 2

No engine problems told at all ? IS THERE?
what an easy question . RTM is what to do read the manual. on car
called service manual, pay $20 and read it online. like all techs do.

1: well the service manual covers every one of those for sure P1xxx
factory codes. 2002 year, car.
chev. 1500? 1500HD , 2500 or 3500???????? al in HD format too.
no car told but lets do 1500 only 5.3., VIN Z automatic box.
as a rule low codes are first.
140 is
HO2S Circuit Insufficient Activity Sensor 2 174 is
Fuel Trim System Lean Bank 2, humm due to above sure. 332 =
Knock Sensor (KS) Circuit Low Voltage Bank 2 so lean burns cause knock cause 174 and knocks , expected.
1133=
HO2S Insufficient Switching Bank 1 Sensor 1 oops both side fail (banks) hummmmm what can do that, sure low fuel pressure.(and loss of power)
1153 is
HO2S Insufficient Switching Bank 2 Sensor 1
P1157, is missing in my b ook(1500) or was that really P0157?????
HO2S Circuit Low Voltage Bank 2 Sensor 2 all4x O2 fail . failed, but no heater failures 02 seen.
I bet all 4 are not bad but the enigine is hyper lean fueled.

and sensor 1 is front and when it sticks lean, the fuel pressure is low (can be or all injectors are partially clogged or FPR bad.

no statement by you , LOST ENGINE POWER>?
or engine dead.
what's up doc, why are you here, scanning, just for kicks?
and PCM is loaded with old errors never reset.?????
reset them using the tool and see if some come back.
PCM 101 here. ASE. reset it.
fuel rail pressure is spec at, VIN Z engine is

(55-62?psi) VIN: (V, T,U)
the SM has 25 steps for FPR checks and injector balance tests.
the 02 sensors can not adjust for grossly wrong fuel pressure
bad fuel or clogged injectors.
or bad bad spark (plugs , boots wires bead or coil packs)
my guess is low fuel pressure but gee I can't drive it to see that./

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

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

P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Causes for P0332 DTC:
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- PCM or ECM failure.

Solutions:
- Repair or resecure the harness or connector.
- Replace the knock sensor.

Your best bet is to just replace the knock sensor for sensor 2 bank 2. Call Auto Zone with part number SU1282 this is the OEM replacement.

The knock sensor looks like this:

P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

This sensor signals the engine-control computer when detonation is detected, momentarily retarding ignition timing until detonation ceases.

Most computer-controlled systems use knock sensors to ****** timing when the engine is experiencing pinging or knocking.


Obviously, a faulty knock sensor produces problems that appear to be ignition-system-related. If the knock sensor system does not provide an engine detonation signal to the PCM (powertrain control module), the engine detonates, especially on acceleration.

• The first step in diagnosing the knock sensor and knock sensor module is to check all the wires and connections in the system for loose connections, corroded terminals, and damage.
• With the ignition switch on, be sure that 12 volts are being supplied through the fuse to the knock sensor module.
• A quick check of a knock sensor is to watch the ignition's timing while the engine is running and the engine block is tapped with a hammer.
  • The noise should cause a change in timing.
• The knock sensor can also be checked by tapping near the sensor and watching for an AC pulse on a DMM or lab scope.

Have you had the engine worked on? this looks like maybe the spark knock sensor is either disconnected or has been overtightened in the block, to check this locate the knock sensor at the base of the cylinder block just above where the oil pan bolts to the block, it is round (with a wire connector going to it) with a large hex nut configuration to pull it out, it is in the water jacket so if you do pull it drain the cooling system and the engine block, if you replace it DO NOT OVER-TIGHTEN IT! tighten to suggested torque setting in factory service manual.
