My check light comes on scanned system found several codes po443 evap,po135 o2sensors all banks,and egr vacuum regulator solenoid circuit can you advise me on next step


the codes should be addressed in the order they show up, so starting with the P0443 (it's a zero not an o after the P, the P refers to a powertrain code).
Have you replaced the purge valve itself, often times this will rectify the trouble.Open the gas cap after driving a while , do you hear a "whoosh" of pressure release? If so likely the valve itself is defective.Replace it reset the MIL and drive to see if light comes back on, if it does ,rescan to see if 443 is still present, if not then move on to new first trouble code.
(fyi)
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

How to retrieve DTC:
The heater control panel has self-diagnosis function. To run the self-diagnosis function, do the following:
1.Turn the blower fan OFF.
2.Press and hold the recirculation control switch and the rear window defogger switch down.
3.Turn the ignition switch ON (ll).
4.Release both switches. The recirculation indicator and the rear window defogger indicators come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is ok, the recirculation indicator stays off.

DTC TROUBLESHOOTING INDEX
DTC (Recirculation indication blinks) Detection Item Page

9A problem in the air mix control linkage, door, or motor.21 - 17
10An open or short in the mode control motor circuit.21 - 18
11A problem in the mode control linkage, doors, or motor.21 -19
12A problem in the blower motor circuit.21 - 20

(THE CONTROL PANEL MUST BE REPLACED).21 - 38
14An open in the evaporator temperature sensor circuit.21 - 23
15A short in the evaporator temperature sensor circuit.21 - 24
- In case of multiple problems, the recirculation indicator will indicate only the DTC with the least number of blinks.
- In case of an intermittent failure, the heater control panel will store the DTC until the ignition is turned off.

P1747 * EPC, wiring, PCM EPC solenoid circuit failure, shorted circuit or output driver Voltage through EPC solenoid is checked. An error will be noted if tolerance is exceeded. Short circuit causes minimum EPC pressure (minimum capacity) and limits engine torque (alternate firm). Go To Pinpoint Test
The EPC solenoid is shorted or the electrical circuit (wiring) or the transistor (driver) inside the computer is fried. do you know how to test a computer controlled circuit ?

Do you know how to find the circuit in question ?

And you are correct about these two codes as being not related . Do you know what evaporative emission system is ?


Wells EVAP Training with Sgt Tech P0440 P0441 P0442 etc

The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test.
EVAP Evaporative Emission Control System - AA1Car.com
http://www.bbbind.com/free_tsb.html you can find free wiring diagrams here . Do you know how to use a wiring diagram ?

P1451 - EVAP Control System Canister Vent Solenoid Circuit Malfunction Monitors the canister vent (CV) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command.
  • VPWR circuit open
  • CV solenoid circuit shorted to PWR GND or CHASSIS GND
  • Damaged CV solenoid
  • CV solenoid circuit open
  • CV solenoid circuit shorted to VPWR
  • Damaged PCM
To verify normal function, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage (PCM control side). With the valve open, EVAPCV will indicate 0% duty cycle and the voltage approximately equal to battery voltage. When the valve is commanded fully closed, EVAPCV will indicate 100% duty cycle and a voltage drop of 4 volts minimum is normal. Output test mode may be used to switch output ON/OFF to verify function. This is another electrical circuit problem .
Do you know how to use a DVOM - digital volt ohm meter ?
Do you know that P1747 (electronic press control solenoid short circuit) Is a transmission problem . This solenoid controls the fluid pressure .

Sharp AR-M237 Error Code H4-21


-H4-21 means:Sub heater lamp abnormally low temperature detection. The setup temperature (about –25°C: Sim 43-1-1) is not reached within the specified time (about 32sec) from turning on the power ON SW. (When the temperature falls below 140°C in the standby mode.)
-Causes:
Sub heater thermistor defect
Sub heater lamp failure
Sub thermostat failure
Control PWB failure
-Check the sub heater lamp blinking with SIM 5-2-2.
When the lamp blinks normally: Check the thermistor and the harness. Check the MCU PWB thermistor input circuit.
When the lamp does not light: Check for disconnection of the heater lamp and thermostat. Check the interlock switch. Check the power PWB and the MCU PWB lamp control circuit.
Clear the display of self-diagnostics with SIM 14.
The H4 errors will not reset by themselves. You must enter service mode to reset this error even if the problem has been repaired. The reset process is outlined below (DO NOT USE ANY OTHER FUNCTIONS IN SERVICE MODE):
Press the following sequence: "#/P" "*" "C" "*"
Type in 1 4
Press start
hit 1 for yes
hit start
Unit should power off and the restart.
If the error code recurrs ther are other problems.
