WHAT ARE CODES PO330 AND PO320 CTS 2006 CADILAC


I use this website all the time:
https://www.obd-codes.com/p0320
https://www.obd-codes.com/p0330
https://www.obd-codes.com/p0420
https://www.obd-codes.com/p0430

Now the art is knowing how to interpret, the P0320 and P0330 can set off your P0420 and P0430 oxygen sensor codes. I would address the P0320 and P0330 first and probably the O2 sensor stuff will probably go away. If your car is knocking, rough idle, loses power, etc. then the 300 codes make sense and you have issues. It could also be two separate issues were damaged wiring on the knock sensors and then a damaged catalytic converter. I've got a car that constantly throws up 420 and 430 codes because the catalytic converter got dinged up from running something other.

Kia Amanti Ignition failure sensor


Code p0320 refers to crank shaft position (CKP) sensor/engine speed RPM sensor-circuit malfunction===causes---wiring CKP/RPM sensor ---ECM. Get your hands on an aftermarket workshop manual for the car and you should be able to replace the items

P0320


P0320 is a code that usually is due to faulty crank sensor, basically the crank sensor is monitored by the computer to adjust timing when driving vehicle, computer completely controls all timing advance and retarding at various points while driving, chances are your sensor is going bad and giving a inaccurate reading causing your engine to have huge lack of power due to improper timing.. May want to check circuits between computer and sensor to assure wiring is ok, does the temperature of the engine seem to make a difference in how it runs???

I have a grand cherokee 2000, at first it used to have the check gauges signal on, and never turn on the engine for a while, just after some hours the signal go and it is start, but now when the engine...


P0320 (M) No RPM Signal to PCM (Crankshaft
A CKP signal has not been detected at the PCM

Try changing your crank sensor. Hope this helps, James Booth

98 wrangler shuts off and won't start intermittently. Codes are P1594, 0320, 0463 & 1391. Do I change the crank senor, cam sensor or fuel filter/regulator??


(this is for others who may be viewing this problem)
P1594 = charging system voltage is too high
P0320 = crankshaft position sensor (CKP)/engine speed (RPM) sensor-circuit malfunction
P0463 = fuel level sensor circuit, high output
P1391 = intermittent loss of CMP (camshaft position) or CKP (crank position) sensor

Probably start with changing the crank sensor. But keep in mind that the high charging system voltage may be causing the other electrical sensor problems. The voltage regulator (probably located internally in the alternator) is not regulating voltage properly. So changing the alternator may be needed as well. Price the parts and start with replacing the less expensive first.

Trouble code P0320 ignition/dist. engine speed input circuit


P0320 - Ignition / distributor engine speed circuit malfunction

The ignition engine speed sensor input signal to Powertrain Control Module (PCM) or Electronic Control Module (ECM) is continuously monitored. The test fails when the signal indicates that 2 successive erratic profile ignition pickup (PIP) pulses occurred.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stall

When is the code detected?
The P0320 code is triggered when 2 successive erratic PIP pulses are detected.

Possible Causes:
- Loose wires/connectors
- Faulty Crank Position Sensors
- Arcing secondary ignition components (coil, wires and plugs)
- Low battery charge
- Powertrain Control Module

Possible Solutions:
- Resecure loose wire or connectors
- If battery charge is low, recharge or replaced battery
- Replaced crank position sensor
- Replaced starter motor


Test it and tell us news.

P0320 & P1391 OBD codes displayed, found during emissions testing but there are NO engine or driving problems idicated.


P 0320 = No Crank Reference Signal to PCM. No Crank (shaft position) reference signal detected during engine cranking (starting).
P 1391 =Intermittent Loss of either Camshaft Position Sensor or Crankshaft Position Sensor.
Hav you attemtped the "3-Key-Ons" method to see these codes on your digital Odometer (assuming you have one) Turn the Key from Off to On (not start) three (3) times. On the third (3rd) time leave the Key in the "On" position (not start). Look at your Dogotal Odometer (if so equipped). The Codes, one at a time should appear. The Last Code will be "P donE".
If te engine is performing without problems: disconnect the negative side of the Battery and wait at least 5 to 30 minutes. Reconnect the Battery. Re-preform the 3-Key-On's and see if and Codes are now showing.
If you start having Start or Running problems becoming more and more frequent: consider replacing the Crankshaft Position Sensor. If this sensor "fails" you may not get any fire to anything, as this is the signal that is necessary for the PCM to initiate the Firing Sequence. The PCM will not send a signal to even the Ignition Coil to begin.

I am getting the codes p0320 and also the code p1299 the truck is shutting down when driving down the road sometimes will start right back up and sometimes you have to wait for a bit and then drive for...


Hello

The codes you are getting:

P1299
- Cylinder Head Over Temperature Protection Active Indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Fail-safe Cooling was activated to cool the engine. Engine cooling system concerns

Causes:
Low engine coolant level
Base engine concerns


P0320 - Ignition Engine Speed Input Circuit Malfunction - The ignition engine speed sensor input signal to PCM is continuously monitored . P0320 indicates that two successive erratic profile ignition pickup ( PIP ) pulses have occurred

causes: loose wires / connectors , arching secondary ignition components ( coil , wires , + plugs ) , on board transmitter ( 2 - way radio )

This is the explanation for the error codes you are receiving, at least it is a good place to start looking for the problem. Hope this can help you.

Kind regards
