      What codes do you have from the check engine light
    • Jimm

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA.

      Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      P0340. Camshaft Position Sensor Circuit Malfunction

      A wire or connector in the circuit could be grounded/shorted/broken

      The camshaft position sensor may have failed

      There exists an open circuit

      The crankshaft position sensor may have failed.

      The powertrain control module may have failed. ( Some local auto parts stores may have the fixture to test the pcm or negotiate it with the store managers to obtain a loaner pcm for a try ).

      Possible causes
      - Harness or connectors (The sensor circuit is open or shorted)
      - Camshaft position sensor may be faulty
      - Camshaft (Intake) may be damage
      - Starter motor may be faulty
      - Starting system circuit
      - Dead (Weak) battery
      Possible solution
      - Charge battery
      - Repair harness or connector
      - Replaced Camshaft Position Sensor.
      Tech notes
      - Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code.
      When is the code detected?
      - The camshaft position sensor signal sent to the ECM is intermittent
      P0344 Description
      The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

      When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

      When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

      P0420 Catalyst System Efficiency Below Threshold (Bank 1)

      Note: replace the Up-stream sensor (located before catalytic converter)
      Down-stream sensor (located after catalytic converter)
      Replace the both sensors as necessary. Check with for the O2 sensors.

      Trouble Code: P0420 Catalyst Efficiency Below Normal (Bank 1)

      Possible Causes:
      Air leaks at the exhaust manifold or in the exhaust pipes
      Catalytic converter is damaged, contaminated or has failed
      Front HO2S or rear HO2S is contaminated with fuel or moisture
      Front HO2S or the rear HO2S is loose in its mounting hole
      Front HO2S is older (aged) than the rear HO2S (HO2S is lazy).

      The P0700 is not a specific fault code, it merely says that there is a fault in the transmission

      More likely the issue is a faulty / blown cylinder head gasket - especially with the overheating condition.

    What would the relation between the air conditioner and the idling of the engine?
    When air conditioning is on and the car is idling (not moving forward) the engine will idle ruffly. If the air is shut off the engine will idle normally.

      The idle air control (IAC) valve is located on the throttle bore (in most cases) and is designed to adjust engine air intake at idle which controls the engine idle speed. The PCM receives feedback data from various sensors to send output signals designed to adjust the air passage open or closed which adjusts the engine idle speed. At engine speeds above idle, the valve is not used and does not effect the engine. Engine idle speeds are not adjustable.

      When an idle air control valve get dirty or fails it can cause the engine to idle erratically and even stall. Sometimes a weak idle air control motor will can cause engine problems without triggering a MIL (check engine) light. Inspect vacuum lines when servicing the idle air control valve and replace any that are broken or dilapidated.

      As the first step - clean the IAC and throttle body, and the MAF sensor using a sensor-specific aerosol spray. Make sure the air cleaner / air filter is clean.

      Check the various on-line vendors;,,, to list only a few. For example, they (RockAuto) list the idle air control (IAC) valve from around $42.00 for your vehicle.

      I'd have to make sure the battery has a full charge. All battery connections clean and tight. Use a digital multimeter across battery posts, everything off, what is the reading?

      Some makes and models, if battery voltage is lost it might effect your security system, where applicable.

      If starter motor issue, check voltage and ground for the starter motor. Any testing at the starter make sure the tranny is in park or neutral and the parking brake is set.

      A code P0401 most likely means one or more of the following has happened:
      The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
      There is a blockage in the EGR (tube), most likely carbon buildup
      The EGR valve is faulty
      The EGR valve may not be opening due to a lack of vaccuum

      P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting).
      Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem.

      Note: If the P0420 code is combined with other codes, try fixing the code P0401 first.
