Describe your 1996 Ford Explorer Problem..trouble

Odometer trouble codes can sometimes be an absolute pain in the tailbone to decode. An option here is to get the vehicle plugged into an OBD2 scanner to check the main ECU for Trouble Codes. These are easier to decode as they are generally used in most vehicles after 1996. Post these codes and we'll try to help you more.
If you have to pay for this service ask at 4 or 5 different places as prices can be VERY different!

Here's a link for codes P0446,P0443. https://www.obd-codes.com/p0446 Here's the link for P0403.

2008 Nissan frontier code po443 what doesit m aen on tell how to fix it how dow I find on the truck thanks

this obd2 trouble code table can help you understand the meaning of code.
If you want to know detail of it and how to solve them, you can buy this DTC manul to check.

Technical Description:
EVAP Control System Canister Vent Solenoid Circuit Malfunction
The EVAP system 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.
Symptoms: You will likely not notice any drivability problems.
Causes: A code P1451 may mean that one or more of the following has happened:
*VPWR circuit open
*Damaged canister vent solenoid
*Canister vent solenoid circuit open or shorted to ground, power, etc.
*Damaged Powertrain Control Module (PCM)
*Possible SolutionsVerify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage
(PCM control side).With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery voltage.
When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal.
Output test mode may be used to switch output on/off to verify function.
*Replace canister vent solenoid

check the vacume lines

That code is for the Evaporative Emissions. It could be a bad Evaporative Emissions Canister Valve or just a bad vacuum line or my granddaughter's 1997 Ford Escort had that code and her gas cap was NOT on. Now when you figure out what one it is disconnect the battery for 10 minutes to reset the computer.

A blinking OD light on a Ford Explorer means that there has been a fault detected in the transmission operation, a common one is excessive slippage detected between input and output turbine shaft speed sensors, this can be a slipping trans, you may not even fell it, but it is indeed slipping, but lets not get ahead here, go to the Ford dealer and have a system trouble code scan run of the on board, this will reveal the trouble code that the blinking light has set in the computer control for the transmission and give direction to what the cause is. I am a veteran 25 year Ford factory trained dealership tech with master technician certification from Ford..

Actually,when the O/D light is flashing,the vehicle is indicating a problem within that specific system.When this happens with any system on the vehicle,a diagnostic trouble code is set in the vehicle computer's memory.What you did by disconnecting the battery was simply to erase the trouble code from the computer's memory.If the transmission feels like it is slipping,it probably is,and that's where the problem will be.You can drive the vehicle,and the code will reset again sooner or later,as will the O/D light flashing.Have the vehicle scanned when the code resets,try not to drive it very hard,because if the trans is slipping,driving it will worsen the damage/cost to repair.
