What does Code P046 mean - 2003 Chrysler Town & Country

the p1000 is a system readiness code meaning the car is checking itself..it means its not finished etc but once it has the code will change to p1111..meaning system check completed, the c1165 is a abs or wheel speed code, check the wheel where this code is originating

Generally speaking, code 12 means the battery has been disconnected at some point in time.
Code 44 means the battery temp sensor circuit is out of normal range, too high or too low.

P0700 means transmission control fault detected,either it is mechanical or electrical.This code is a generic code,you will need a enhanced code that mean a manufacture scantool or a scan tool that can read enhance code.

Maybe you meant a P0406? That is an EGR code. It could be the EGR valve, solenoid or a wiring issue. Check that code again, P codes are always followed by 4 numbers.

it's for a bad coil pack or COP, coil on plug

That means Code 17, one long flash means 1, seven short flashes means 7. The code is for the Vehicle Speed Sensor (VSS) Have it checked and replaced if necessary.

p1405 is a egr code (upstream hose off or pluged)

Codes are usually 3 digits and will start with start with a letter...P(Powertrain), B (Body), C(Chassis) or U(undefined).
The majority of codes are power train codes and I looked at P046 and there is no such code.

The fastest way to find out the problem is go to an auto parts store and ask them to use their code scanner. They tpically will do this for free and then tell you what the codes mean.

P0442 EVAP Leak Monitor .040 Leak Detected (Medium Leak)

P0456 EVAP Leak Monitor .020 Leak Detected

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.

Just replace the air flow meter.That sounds like your problem.
