the following information courtesy of OBD-CODES.com P0328 Knock Sensor Circuit High Input OBD-II Trouble Code Technical Description Knock Sensor 1 Circuit High Input (Bank 1 or Single Sensor) What does that mean? 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 retard the spark timing to avoid pre-detonation. Most PCMs have the ability to learn spark knock trends in the engine during normal operation. A P0328 code is a generic DTC, thus it applies to all makes of vehicles, and refers to a high output voltage of the knock sensor. In many cases, this means the voltage is above 4.5V but that specific value depends on the specific make and model of vehicle. This code refers to the sensor on bank #1. Symptoms Symptoms of a P0328 DTC may include: MIL (Malfunction Indicator Lamp) illumination Audible knocking from the engine compartment Pinging from engine under acceleration Loss of power Irregular RPM Causes Potential causes of a P0328 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 Loose knock sensor Electrical interference in circuit Low fuel pressure Incorrect fuel octane Mechanical engine problem Failed/faulty PCM Possible Solutions If you can hear engine knock (detonation), first fix the source of the mechanical problem and retest. Ensure the correct octane fuel was used (some engines require premium fuel, check the owners manual). Aside from that, for this code, most likely the problem will lie either with the knock sensor itself or the wiring & connectors going from the sensor to the PCM. Realisitcally, for the DIY vehicle owner, the best next steps are to measure the resistance between the two knock sensor wire terminals where they go into the PCM. Also, check the voltage of the same terminals. Compare those numbers to the manufacturer's specifications. Also, check all wiring and connectors leading from the knock sensor back to the PCM. In addition, you should also check the resistance using a Digital Volt Ohm Meter (DVOM) of the knock sensor itself, compare it to the vehicle manufacturers specification. If the knock sensor resistance value is out of spec, then it needs to be replaced. Other knock sensor DTCs include P0324, P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0332, P0334 Register now to ask a question (free) Related P0328 DTC Discussions

P0133 Ford O2 Sensor Circuit Slow Response Bank 1 Sensor 1

DTC P0133 - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)
This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use. You will likely not notice any drivability problems, although there may be symptoms.

A code P0133 may mean that one or more of the following has happened:
The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak


DTC P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
This code refers to the front oxygen sensor on Bank 2. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0155. See also: P0135 (Bank 1). You will likely notice poor fuel economy the illumination of the MIL.

A code P0155 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness


DTC P0306 - Cylinder #6 Misfire Detected
A P0306 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6. Symptoms may include the engine may be harder to start, the engine may stumble / stumble, and/or hesitate or other symptoms may also be present.

A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer


DTC P1115 - Intake Air Temperature 2 Circuit High Input (Super/Turbo Charged engines)


In the next diagram could checl this specific location about each O2 sensor...




Hope this helps.

P1131 is "Lack of H02S-1,1 Switch, Sensor indicates lean" I'd say you've got a bad Heated Oxygen Sensor at Bank 1, Sensor 1.

P0340 OBD-II Trouble Code - Camshaft Position Sensor Circuit Malfunction

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
* Hard starting or no start
* Rough running / misfiring
* Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
* a wire or connector in the circuit could be grounded/shorted/broken
* the camshaft position sensor may have failed
* the PCM may have failed
* there exists an open circuit
* the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Visually inspect all the wiring and connectors in the circuit
* Check for continuity in the circuit wiring
* Check the operation (voltage) of the camshaft position sensor
* Replace the camshaft position sensor as required
* Check the crankshaft position circuit as well
* Replace circuit wiring and/or connectors as required
* Diagnose/replace the PCM as required



P0133 OBD-II Trouble Code - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms: You will likely not notice any drivability problems, although there may be symptoms.

Causes: A code P0133 may mean that one or more of the following has happened:
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
* Check and fix any exhaust leaks
* Check for wiring problems (shorted, frayed wires)
* Check the frequency and amplitude of the oxygen sensor (advanced)
* Check for a deteriorating / contaminated oxygen sensor, replace if necessary
* Check for inlet air leaks
* Check the MAF sensor for proper operation


Hope this helps (remember to rate this answer).

P0705
Transmission Range Sensor "A" Circuit (PRNDL Input)

HI. Lets start with the P0133 Code:

This code is in reference to the O2 sensor that is behind the catalytic converter(down stream sensor). You will need to test the connecting harness that links that sensor to the ECM for shorts. If the harness is ok, simply, replace that sensor.I would also advise to check for any apparent exhaust leaks as well and for proper MAF functions. You will more than likely have to replace the sensor, but ti be safe, check the areas I have stated first before you replace it.

Now, lets move on to the next code. This will be the P0705:

This code is in reference to the park/neutral position switch circuit. The only recourse here will be to replace that switch. It has failed.

I just came from an Autozone, and then spoke with 2 Hyundai dealership service departments and they all three stated the P0113 code is the Intake Air Temperature sensor (IAT, also referred to as the Mass Air Pressure - MAP - sensor) on the engine, not an O2 sensor found in the exhaust system.
