Just had my 1999 Kia Sephia fixed purge control valve and air hose check engine light back on giving code p0101

Robert, High emissions usually mean the EGR valve and several hoses and other smog components are clogged up. There is no easy fix, you have to get the shop to check through the smog system on your car if you cannot do it yourself. Type of driving, short runs, high miles, burning oil etc all contribute to the engine giving a dirty reading. It may not be enough to light the lamp but it'll be dirty enough. Of cause, it may be the lamp is bust as well? Does it test light when you start up?

PO402--EGR Flow Excessive Detected

There are other components besides the
egr valve in that sytem,so you got things to
diagnose there you skipped over

PO443---Evap Control System Canister Purge

Valve Circuit Malfunction


PO1409--EGR Vacuum Regulator Solenoid
Circuit Malfuntion


PO420 & PO430--Catalyst System Efficiency
Below Threshold---Basically worn out exhaust
converters you will need to replace


Advice--take to a repair shop & go thru the entire
car & resolve ALL Issues

You will need to get it scanned and get the codes for the problem. If it failed the test due to emissions I would almost guarantee it will be your oxygen sensor or cat

check the number 10 fuse should be a 15a but it says open in th emanual but it was not on mine see link

No any codes will let you fail..Rangers are bad about the valve sticking..But first look on th driverside very back on the intake..Youll see a valve with two vacuum lines The one that goes on the bottom of the valve makes a 90 bend and is bad about breaking..If the lines are good then work the valve by hand and see if it will move

It will not pass inspections. The purge valve could be a vacuum hose cracked or something simple but it could also be a worn out valve. The pcm failure could be very expensive.

take you car to an auto parts store that checks your check engine code for FREE most of the chains do.take a pen and paper thats in case they cant give you a print out .you need the codes and what they are also get the trouble shooting tips for those codes .if you still need more help repost with the codes and what they are..... example p0100 mass air flow circuit malfuntion.todays cars all start with those codes it help you narrow down the problem

A code P0441 could mean one or more of the following has happened:

• Bad vacuum switch
• Broken or damaged EVAP line or canister
• Open in PCM purge command circuit
• Open or short in Voltage feed circuit to Purge Solenoid
• Faulty purge solenoid
• Restriction in EVAP solenoid, line or canister
• Corrosion or resistance in purge connector
• Bad PCM Evaporative Emission Control System Incorrect Purge Flow
  What does that mean? This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister
  , purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
  EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank
  into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.

Hi:
Your P0446 code is a Evap vent valve code: Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.
Symptoms There will be no obvious symptoms to driver, other than MIL illumination.
Causes A code P0446 could mean one or more of the following has happened:

• Faulty vent valve
• Open, short or excessive resistance on Vent valve control circuit
• Blockage of vent valve
• Bad PCM

Possible Solutions With a P0446 OBD-II trouble code, here are some things to try:

• Replace Vent valve
• Repair open, short, or resistance problem in control circuit
• Repair open, or short, or resistance problem in power circuit
• Replace PCM
