I need to know what code p0326 means for a 2001 kia sportage. i know it a knock sensor code what do i do with information.

These codes refer to 3 different issues.
P0053 - HO2S Heater resistance Bank 1, sensor 1.
P0054 - HO2S Heater Resistance Bank 1 Sensor 2
P0324 - Knock Sensor (KS) Module Performance.
P0326 - Knock Sensor Circuit Excessive Spark Retard.
P0597 - Thermostat Heater Control Circuit Open.

You need to get a good mechanic to look at this. The HO2S codes refer to both of the 'O2' sensors in the exhaust, (mounted before and after the Catalytic Converter). They monitor the exhaust gas mixture to correct fuel mixture to the engine to control exhaust gas pollution levels. If one is detecting a wrong reading, the fuel/air mix is automatically adjust.
The Knock sensors detect vibration from when the fuel is burning. If the sensor detects a 'bang' when it shouldn't be there it alerts the ECM (cars brain) to adjust the timing sequence.
Wrong readings cause the ECU to adjust the fuel/air mixture to the wrong setting causing rough engine running.
The thermostat code is for the wiring to the coolant thermostat sensor.

codes p 0352--353--354 all refer to ignition coils B, C, D--circuit malfunction=== causes --wiring---ignition coil --ECM
codes P0326, 327 ,328 all refer to knock sensor 1, bank 1 range / performance , for 326, --low input for 037 and high input for 0328=== causes --wiring---knock sensor(KS)incorrectly tightened --0326, insecure KS , poor connection, wiring short to ground , incorrectly tightened---ECM and for 0328--wiring short to positive --KS incorrectly tightened---ECM
It seems strange that all these codes appear and unless you have done work on the engine previously to these codes appearing, I would first replace the ECM with a known good unit, remove the codes then run the vehicle again for 15 minutes to see if the codes reappear

It's is P0326 knock sensor range performance . Basically the sensor needs to be replace. Sorry not much help, if you want more info I need to know make,model,year

1. Remove the intake manifold support bracket
2. Disconnect wire harness
3. Loosen bolt remove harness

P0326 - Knock Sensor 1 Circuit Range/Performance (Bank 1 or Single Sensor) High Voltage
Knock sensors are used to detect engine pre-detonation (engine knock or ping). The knock sensor (KS) is usually a two wire sensor. A 5 volt reference is supplied to the sensor and there is a signal return from the knock sensor to the PCM (powertrain control module). The sensor signal wire informs the PCM when a knock occurs and in what degree of severity. The PCM will ****** the spark timing to avoid pre-detonation. Most PCMs have the ability to learn spark knock trends in the engine during normal operation.

If the PCM determines that the knock is out of the ordinary or that the noise level is abnormally high, P0326 may set. If the PCM senses that the knock is severe and cannot be eliminated by retarding the spark timing, P0326 may set. Keep in mind that knock sensors cannot distinguish between a knock from pre-detonation or one from engine problems.

Symptoms of a P0326 DTC may include:
MIL (Malfunction Indicator Lamp) illumination
Audible knocking from the engine compartment
Pinging from engine under acceleration

Potential causes of a P0326 code include:
Knock sensor connector is damaged
Knock sensor circuit is open or shorted to ground
Knock sensor circuit is shorted to voltage
Knock sensor has failed
Moisture in knock sensor connectors
Incorrect fuel octane
PCM has failed

Possible Solutions:
If an engine knock can be heard, fix the source of the mechanical problem first then retest. Make sure the proper octane of fuel was used in the engine. Using lower octane fuel than what is specified can cause a ping or pre-detonation and may cause P0326.

Unplug the knock sensor and check for water or corrosion in the connector. If the knock sensor has a seal, verify there is no coolant from the engine block fouling the sensor. Repair as necessary.

Turn ignition to run position with engine off. Ensure that 5 Volts are present at the KS connector. If there is, check for proper resistance between KS terminal and engine ground. You will need a vehicle specification for this. If resistance is out of specification, replace the knock sensor. If resistance is normal, plug KS back in and idle the engine. Using a scan tool in datastream, observe KS value. Does it indicate a knock is present at idle? If so, replace the knock sensor. If the knock sensor shows no knock at idle, then tap on the engine block while observing the knock signal. If it doesn't show a signal that corresponds with the taps, replace the knock sensor. If it does, verify the knock sensor wiring isn't routed next to ignition wires. If there was no 5 volts present at the knock sensor connector while unplugged with KOEO (Key on engine off) then go back to the PCM connector. Turn ignition off and clip the knock sensor 5 volt reference wire in a location that is easy to repair (Or remove the wire from the PCM connector). With KOEO, check for 5 volts on the PCM side of the clipped wire. If 5 volts isn't present, suspect a bad PCM. If 5 volts IS present, repair short in 5 volt reference circuit.

Since the reference circuit is a shared circuit, you will need to check all engine sensors that are fed a 5 volt reference. Unplug each sensor one at a time until the reference voltage returns. When it returns the last sensor you plugged in is the shorted sensor. If no sensors are shorted, check the wiring harness for short to voltage on reference circuit.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Your local auto parts store, or auto parts superstore should have it, if not, be able to order it. Ex.--Advance Auto Parts store has a BWD Knock Sensor, #S8815, for around $50.00. 2002 Kia Rio 1.5L/L4/FI

Assuming a first generation Sportage, sounds like a problem with the vehicle speed sensor on the back of the transfer case (4wd) or transmission extension housing (2wd).

Could be as simple as a corroded/broken wire, through to a malfunction in the sensor. Take it to Autozone and get the codes read and let us know what they are (to be absoluteluy sure...).

You will need to do an obd 2 scan. You can do this at advance auto or autozone. Its a sensor problem. Once you find out the code of what sensor is bad, you replace it

You might want to check your knock sensor because if that out your engine doesent know how air to take in or how much gas to give , Thats why your waistting gas

the knock sensor is on the pass side of the motor slightly back from the oil filter on a stand off on the block. tricky to get to but you loose no coolant changing it.
