What are possible causes of P1768 code on a 2001 Chrysler PT Cruiser?


Do the easiest things first:
Check the battery earth lead (bear in mind that if you disconnect the batter you will probably have to re-enter the radio code). Check where it connects to the body/engine block - make sure it is clean and secure.

Then check every other earth lead you can find

P0443 Evaporative Emission Control System Purge Control Valve Circuit
P0443 - Evaporative Emission Control System Purge Control Valve Circuit

Copyright © OBD-Codes.com
The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter the engine to be burned, rather than vented into the atmosphere as an emission. The purge valve solenoid is supplied switched battery voltage. The ECM controls the valve by operating the ground circuit, opening the purge valve at specific times allowing these gasses to enter the engine. The ECM monitors the ground circuit as well, watching for faults. When the purge solenoid isn't activated, the ECM should see a high voltage on the ground circuit. When the solenoid is activated, the ECM should see the ground voltage pulled low, close to zero. If the ECM doesn't see these expected voltages, or senses an open in the circuit, this code is set. Note: This DTC is similar to P0444 and P0445. Potential Symptoms P0443 trouble code symptoms could be just an malfunction indicator lamp (MIL) illumination. There may be no drivability problems at all. But, it's also possible to have a lean condition or a rough running engine if the purge valve is stuck open. Usually though, these symptoms are accompanied by other EVAP codes. Another symptom may be excessive pressure in the gas tank in the form of a "whooshing" sound when the cap is removed, indicating a purge valve that isn't working at all or stuck closed. Causes To cause a P0443, there has to be a problem with the purge control CIRCUIT, not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following: Bad purge solenoid (internal short or open) Wiring harness chafing or rubbing another component causing short or open on control circuit Connector worn, broken or shorted due to water intrusion Driver circuit inside powertrain control module (PCM) is bad Possible Solutions 1. Using a scan tool, command the purge solenoid to activate. Listen or feel for a clicking coming from the purge solenoid. It should click once, or on some models it may click repeatedly. 2. If it doesn't click with scan tool activation, unplug the connector and examing the solenoid and connector for damage, water, etc. Then check for battery voltage on the feed wire with the key on. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. If it does, then you know the solenoid is working properly but there is a problem with the control circuit. If it doesn't click when you manually ground it, replace the purge solenoid. 3. To check for a problem on the control circuit (if the solenoid tests okay and you have voltage to the solenoid) plug the solenoid back in and remove the control circuit (ground) wire from the ECM connector (If you're unsure how to do this, do not attempt). With the ground wire removed from the ECM, turn the key on and then manually ground the Purge valve control wire. The solenoid should click. If it does, then you know there is no problem with the control wire to the solenoid and there is a problem with the ECM purge solenoid driver circuit in the ECM. You'll need a new ECM. However if it doesn't click, then there must be an open in the wiring between the ECM and and the solenoid. You must find it and repair it.

Reduced power light trailblazer


Sounds like a bad altenator. Usally accompanied by starting problems. To check the altenator, disconnect the battery while the vehichle is running, if the engine dies when you disconnect the battery, then you'll be looking at a bad altenator. If altenator checks good, then post back with a more detailed description of symptoms.

My 2004 Kia Optima has a code P0443 and I know what it is. There's a hole where air is getting in and I need to know how to find it


Hi, 443 is not a leak--it a purge valve malfunction. Usually the solenoid packs up, but it could be wiring or the connector. You need to disconnect the valve and apply battery voltage to it to see if the solenoid will click. If it clicks, the problem is wiring. If not, replace the purge valve/solenoid. Please let me know if you have questions.

    Hi i have 1997 nissan maxima, emmision test got fail because of P0443 code, it runs well, could you help me tofind solution


    P0443 - Evaporation Emission Control System Purge Control Valve Circuit

    Hi. This code is referring to a malfunctioning Valve circuit, or defective purge solenoid.

    The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter the engine to be burned, rather than vented into the atmosphere as an emission(emission control device). The purge valve solenoid is supplied voltage by the battery, and regulated by a switch. The ECM controls the valve by operating the ground circuit, opening the purge valve at specific times, thus, allowing these gasses to enter the engine. The ECM monitors the ground circuit as well, watching for faults. When the purge solenoid isn't activated, the ECM should see a high voltage on the ground circuit. When the solenoid is activated, the ECM should see the ground voltage registered as a low current, close to zero. If the ECM doesn't see these expected voltages, or senses an open circuit, this code is issued.

    SYMPTOMS:

    Symptoms could be just a malfunction indicator lamp (MIL) illumination. There may be no driving issues at all. But, it's also possible to have a lean condition or a rough running engine if the purge valve is stuck open. Usually, the symptoms are accompanied by other EVAP codes. Another symptom may be excessive pressure in the gas tank in the form of a over pressured sound when the cap is removed, indicating a purge valve that isn't working at all or stuck closed.


    CAUSES:

    1. Bad Solenoid(mechanical failure, or shorted circuit)
    2. Shorted control circuit, or bad harness connection
    3. Water Damaged connection
    4. Bad ECM/PCM


    SOLUTIONS:

    1. It is possible to use a diagnostics scan CPU to command the purge valve to operate, manually. Listen or feel for a clicking coming from the purge solenoid. It should click once, or on some models it may click repeatedly.

    2. If it doesn't click, unplug the connector, and examine the solenoid and connector for damage(water). Check for battery voltage on the feed wire with the key on. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. If it does, then you know the solenoid is working properly but there is a problem with the control circuit. If it doesn't click when you manually ground it, replace the purge solenoid. If it dose click, this will confirm that the solenoid is functional, and the ECM/PCM will be the culprit(Damaged control circuit).

    Po147


    P0147 - 02 Sensor Heater Circuit Malfunction (Bank I Sensor 3)

    O2 (Oxygen) sensors contain a heating element that allows the sensor to reach operating temperature quickly. This lowers emissions since it allows the engine to reach closed loop faster and also allows the engine to stay in closed loop at idle. The heater circuit is supplied a 12 V battery feed from the PCM or ignition circuit (depending on model) and a ground. The PCM (powertrain control module) monitors how long it takes for the sensors to become active after engine start-up. If it takes too long for the o2 sensors to reach operating temperature, this P0147 can set.

    Symptoms: For this particular o2 sensor, there may be no noticeable symptoms other than:
    * MIL (Malfunction Indicator Lamp) illumination
    * Poor/ rough idle

    Causes: Potential causes of an P0147 code include:
    * Bad o2 sensor heater circuit
    * Bad o2 sensor
    * Wiring harness problems

    Possible Solutions: Unplug the Bank 1, 3 sensor. With KOEO (key on engine off) use a voltmeter to check for battery voltage present at the o2 sensor connector (PCM side). (You can also do this with a test light. Connect to ground and touch lead to heater circuit supply. Light should illuminate with KOEO) You should have battery voltage present.

    a. If voltage is present, check the ground side of the heater element also making sure a good ground is present. If it is, check for any faulty connections & then replace the o2 sensor. If you don't have a good ground, then there is an open in the ground circuit somewhere that will need to be repaired. Look for wiring harness contact with exhaust components or broken/missing connectors, etc.

    b. If battery voltage isn't present with KOEO, check for a blown fuse supplying the heater elements. You may need to get a wiring diagram for this. If the fuse is blown, you'll need to check for a short to ground on the battery supply circuit before replacing the fuse. If you find none, and replacing the fuse re-establishes battery voltage at the o2 sensor connector, then the o2 sensor may have shorted internally, blowing the fuse. Replace it & recheck. (NOTE: it's possible for an o2 sensor's heater circuit to be open/shorted and the o2 sensor to still function).

    c. If you have no battery voltage present with KOEO and there are no blown fuses supplying the heater circuit, then check for an open on the supply circuit. You can do this by ohming the circuit with the o2 sensor unplugged and the PCM unplugged. Repair and recheck.


    Hope helps (remember to rate this answer).
