SOURCE: i have volvo v70 with obd codes

PO505 is idle control system malfunction. PO446 is evaporative emissions ( evap) vent system performance . PO443 is evaporative emission control sytem purge control circuit malfunction. PO135 is O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) PO141 is 02 Sensor Heater Circuit Malfunction (bank 1 sensor 2) Now what does all this mean. It means your O2 sensors are being effected by a problem upstream. Could be a many things. If the engine runs perfect then it may be one bad O2 Sensor but it may not. My advice is to have this diagnosed by a trusted mechanic who has the tools, skill, and knowledge to find the problem and not just throw parts at the problem. You can spend lots of money on this unless you know exactly what is causing all these codes.

I have a truck that popped up a P0443 code up and I've been trying to see what it is so I can get it fixed thank yo


P0443 - Evaporative Emission Control System Purge Control Valve Circuit Malfunction

Possible causes: - Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection

When is the code detected? An improper voltage signal is sent to Engine Control Module (ECM) through the valve.
Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
P0443 Description: The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

DAIHATUS MIRA ENGINE CHEK LIGHT ON CODE P0443


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.

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.

I am getting p0030 , p0036. po102 and p0443 on my 2007 chevy uplander ,


I think the first thing I would do is clear the codes and see how many come back after you drive it.
Code 30 and 36 are for the heater circuit in the O2 sensors on bank one. I doubt it would be both sensors, so it may be a wiring problem.
Code 102 is for a low signal from the mass air flow meter which could also be a wiring problem or the sensor or a dirty air filter.
Code 443 is for a problem with the evap purge solenoid circuit which again could be a wiring problem or the solenoid.

I HAVE A QX4 2000 MODEL.WHAT IS THE MEANING OF P1130 SWIRL CONT SOL/V ;AND P0443?


According to Nissan, each cylinder has a valve in the intake manifold to control the air volume in the intake. The code is for one of the swirl control valve solenoids.
Code 443 is for the EVAP canister purge volume control solenoid which is a part the computer uses to vent the gas tank.
I would recommend a shop for both codes.

My 99 expedition shuts off when I put it in reverse and shuts down when I have to stop fast at a red light. I have codes p0443 and p0441 on. Someone please help


P0443 code, EVAP system control purge control valve circuit failure, p0441 is related to p0443. if you fix it, both codes should be gone! to fix p0443-- Using a scan tool, command the purge solenoid to activate. Listen or feel for a clicking coming from the purge solenoid, 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.

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.
