2008 Mdx Radio Code

| Posted on by



Poker night 2 g2a

The CD changer on my 2003 Acura MDX had been randomly flashing ErE1 when switching CDs. This was a problem when I purchased the car (second had from Burrard Acura in Vancouver, Canada). Prior to purchase, the dealer promissed to fix it, or replace the unit. Long story short, they didn’t, and I’ll never purchase a vehicle from Neo Wang and his manager Stanley Fung at Burrard Acura ever again. And yes, I’m a little bitter about it.

Back to the issue, the problem is related to power. The closest I got to solving this problem was when I took the unit to a very good repair shop who got the unit working on their test bench, but could not get it working, minutes later in the truck. The tech brought out a multi-meter and discovered that the unit was not getting enough power to change CDs, jamming the changer, and causing the error.

I need code to unlock my radio and navigation system of my acura mdx 2001 model,with V.I.N 2HNYD60 and with radio serial number 30010445.pls i will be grateful if my request is granted. You can get the code on the link below.

The solution was to work around the problem. I purchased a USA-SPEC PA11-HON adapter which let me interface my iPod with the stereo. As it turns out, there’s a port on the back of the stereo which allows you to hook up a second CD changer. The USA Spec device, plugs your iPod into this port, mimicking a CD changer. So you can listen to your iPod, use the controls on the steering wheel, and map iPod playlists to the CD buttons on the stereo.

The Acura MDX forum went a long way towards helping me solve this problem, and for further information, I’ll send you to the source.

Good luck:

This page is meant to help you troubleshoot the Acura MDX P0420 trouble code. It covers P0420 meaning, symptoms, causes, and possible solutions. WIth the MDX, OBDII P0420 is often caused by a bad oxygen sensor, but there can be other causes as well. Jumping straight to replacing the O2 sensor can cost you time and money. P0420 is the most common OBDII code there is.

Hey guys, I'm a new user to this site. I own a 2008 Mdx with the tech package. My Gps will not work at all. I have reset fuse number 5 and fuse number 32. Still my GPS is blank nothing going on. Number 5 seemed to reset the radio which was already working fine. I just had to enter the code.

Acura MDX P0420 OBDII Code Defined

P0420 is a OBDII trouble code. The code technically stands for:

Catalyst System Efficiency Below Threshold

Acura mdx radio code error

Your MDX has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.

When the readings from the upstream and downstream oxygen sensors show similar readings, the vehicle will throw the service engine soon light (P0420).

These readings shouldn’t match, since the catalytic converter is supposed to be scrubbing the exhaust. When the numbers match, the software in your MDX believes that the catalytic converter is no longer doing its job.

Acura MDX P0420 Code Symptoms

The P0420 code in a Acura MDX will often be thrown one of your oxygen sensors are not functioning properly. Typically, the code will be triggered by the upstream oxygen sensor (before the converter).

There aren’t usually any drivability issues associated with P0420. For most people the first sign that anything is wrong at all is the service engine soon light coming on.

Here are the typical symptoms that something is wrong when you have code P0420.

  • Fuel Efficiency- May or may not suffer depending on how much the catalytic converter is clogged.
  • Loss of Power– It is a really strange feeling to drive a vehicle with a catalytic converter that is going out. Typically, they’ll idle ok and drive normal under a light load. Whenever the engine is put under a heavy load it’ll feel like it is running out of gas. It’s very similar to the symptoms of a bad fuel filter.
  • Service Engine Light– Often, this is the only symptom of the Acura MDX P0420 code.

Top Causes and Solutions of P0420 in the Acura MDX

There are many things that can cause the P0420 trouble code in your MDX. Here are the most common ones.

Often, the oxygen sensor is the cause of P0420. Specifically it’ll usually be the O2 sensor(s) on the upstream side of the catalytic converter. Essl etimetracklite 6.5 license key. But, don’t be surprised if it’s not. It would be a good idea to check the exhaust for leaks first. You should be able to hear an exhaust leak easily underneath of the vehicle.

Unless you have an exhaust leak, you’ll probably need to test the O2 sensors and/or catalytic converters. Here are a couple of good guides to help with that.

Oxygen Sensor

When the oxygen sensor is bad, it can cause a false reading and trigger the code. If the engine does not exhibit any of the decreased performance associated with a bad catalytic converter, it very well may be the oxygen sensor (if you haven’t noticed the performance loss yet).

Catalytic Converter

A catalytic converter is responsible for scrubbing out as much pollution as possible from the MDX’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.

O2 Sensor Wiring

Over time, the oxygen sensor wiring can go bad. It is especially volatile since it is right next to the hot exhaust at all times. The downstream oxygen sensor wiring is also volatile since it is so far from the ECM (more distance to travel = more area to fail).

Timing

If your MDX is misfiring or the exhaust timing is off, this can affect the gasses that are actually going to the O2 sensors enough to cause the P0420 code to register.

Exhaust Leak

If there’s a noticeable exhaust leak coming from the vehicle it can change what the O2 sensors register enough to throw the P0420 code.

If the computer doesn’t know what the engine temp is it’ll keep the fuel mixture rich. When the fuel mixture is rich, the exhaust the O2 sensors see will be out of range and it could throw the sensor.
