Code p 0330 refers to knock sensor(KS) 2 bank 2 --circuit malfunction===causes ---wiring--KS--- ECM
the knock sensor operates by sensing preignition detonation (uncontrolled spontaneous combustion) that is cause by timing and incorrect air/fuel ration
That is reported to the ECM so that adjustments can be made to bring the system back to preset parameters and stop the problem
besides being a knock sensor , it may be also a problem heated oxygen sensor (HO2S) in the exhaust manifold before the cat converter which reports to the ECM the combustion gas composition for adjustment to the air/fuel ratio

95 sl500 check engine light reset and comes back on after it sits over night. any idea?


What code is it throwing ? Some codes are what are called two trip codes ! You clear the codes an start an drive the vehicle ,no check engine light . Park the vehicle over night an bam next time you start an drive the vehicle the check engine light comes back on .

??There are two types of DTC's, 1 trip DTC's and 2

trip DTC's

??A 1 trip DTC is for a condition that requires

immediate attention such as a catalyst damaging

misfire.

??A 2 Trip DTC is one that a condition must be found

during 2 consecutive trips such as an EGR fault.

??Most Monitors do not set a DTC and light the MIL

when a vehicle fails a test for the first time during a

DRIVE CYCLE. If a test is failed on a second

consecutive DRIVE CYCLE the MIL will light and a

DTC is stored in the vehicles powertrain control
module (PCM).

FAIL, no engine stated, we cant open the hood and look, you must.
and no country stated, some countries use different smog parts.

why ask this out of context, you have symptoms,
you have DTC errors.?
what makes you think there is one, (books, guessing, net rumors)
?

let me guess.. P07xx , see those are A/T errors.!!
no code , no joy.
nor is the engine type stated,.
nor which transmission.
that is correct, if the CEL glows running the smog tests is born DEAD.
HOPELESS case. that, so scan it, and post the DTCs.
we wait. now for ever just to get the DTC, post it for helpl.
or GET NONE!
some cars glow the OD lamp or the Drive light, to show errors.
if yours does, nows the time to say so../...\

if you came to my shop?
id know its USA smog fail. and CEL glowing.....all the time...
and open the the hood, and see what engine is there, UN-SAID.
and scan it and see the codes, and drive it and see the tranny (if A/T) mess up.
what codes are you getting?

My 2001 vw jetta wont pass smog, failed on emissions part..check engine light is on for multiple things do I need to fix all to get car to pass smog? Fuel injectors and O2 sensor.


ALWAYS PERFORM TESTS AND REPAIRS ON THE FIRST DTC AND RETEST AFTER EACH STEP.ONE SENSOR OR COMPONENT FAILURE CAN CAUSE OTHERS TO FAIL AS A RESULT.MEANING THE FIRST CODE COULD HAVE CAUSED THE OTHER CODES TO CYCLE.SO ALWAYS DIAG THE FIRST CODE STORED AND EACH ONE AFTER AS THEY WERE READ DURING THE SCAN

GMC 4.3L DTC P0330 flashing MIL


P0330 - Knock Sensor 2 Circuit Malfunction (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 wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0330 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325.

Symptoms: You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.

Causes: A code P0330 most likely means one or more of the following has happened:
The "B" knock sensor is faulty and needs to be replaced
There is a wiring short/fault in the knock sensor circuit

Possible Solutions:
Check the resistance of the knock sensor on bank 2 (compare it to factory specs)
Check for broken/frayed wires leading to the sensor
Replace the knock sensor on bank 2


Hope helps.
