Common Can-Am Maverick Fault Codes

Common Can-Am Maverick Fault Codes

The Can-Am Maverick is one of the most impressive UTVs on the market, but like any vehicle, it has its problems. Every so often, a fault code is going to pop up, and you’ll need to know what it means and how to fix it before you’re able to get back out on the road. 

There are thousands of Can-Am Maverick fault codes, but the most popular ones are P0234, P0261, P0230, P0363, and P0562. Each of these codes indicates a unique problem with the Can-Am Maverick that you should address immediately to avoid engine failure. 

This article outlines some of the most common Can-Am Maverick fault codes and how to fix them. Let’s get started! 

1. P0234

The P0234 fault code is common in many vehicles, including the Can-Am Maverick. It signifies an “Engine Overboost” condition and appears if the Engine Control Module detects an intake pressure higher than the maximum specified pressure by at least four psi. The overboost pressure must last more than five seconds for the fault code to appear (source).  

More often than not, this fault code appears because the boost sensor incorrectly reads the input pressure. When this is the case, replacing the boost sensor solves the problem. 

This fault code might also indicate the need to do one or more of the following actions: 

  • Replace wastegate control solenoid.
  • Replace the wastegate valve.
  • Replace the wastegate hoses.
  • Repair any kinks or damage to wastegate hoses.

Ignoring this fault code can result in engine failure, so it is best to take it seriously and address the issue immediately.

2. P0261

This code signals that something is wrong with the number 1 cylinder because it is delivering a lower reference voltage than it should. When this fault code occurs, potential problems include: 

  • A broken spring inside the fuel injector in the cylinder
  • A connection issue within the wiring connected to the number 1 cylinder 
  • Powertrain control module failure

You can clear this fault code by replacing the fuel injector, repairing any broken wiring, or replacing the powertrain control module. 

If you don’t address the P0261 fault code, you risk damaging your engine irreparably. 

3. P0230

Another common fault code in the Can-Am Maverick is P0230, which indicates that the primary circuit in the fuel pump is not working properly (source). 

A typical indicator of primary circuit malfunction is the fuel pump circuit voltage being lower than it should be. Other indicators are the “Check Engine” light being on and the engine not starting at all. 

When you encounter this code, the usual remedy is to replace your fuel pump. Here’s a general idea of how to do it: 

  1. Remove the fuel line. 
  2. Twist off the retainer ring. You may need a pair of pliers to help you. I recommend the Black+Decker Slip Joint Pliers (link to Amazon). They have a slip-resistant tongue, and the grips are oil-resistant and double-dipped, meaning you can hold them comfortably, and they won’t slip. Their low-profile design also allows them to fit into tighter spaces. 
  3. Lift the pump assembly out. 
  4. Take off the cover at the bottom of the fuel pump assembly, exposing the pump itself. 
  5. Unplug the pump from the pump assembly. 
  6. Put the new fuel pump in place and connect it like the old pump. 

If you are not confident performing the above steps, I recommend consulting a mechanic for help. 

4. P0363

The P0363 code appears when there is a misfire in the cylinder. If you’re seeing this code, the powertrain control module has already cut off the fuel supply to the cylinder because it isn’t working (source). 

The powertrain control module will assume there has been a misfire in many situations, including if the crankshaft position is abnormal or if the engine revolutions per minute are unusual. In addition to the P0363 code, you may notice a reduction of power and struggling acceleration. The “Check Engine” light will also turn on.  

Several problems can result in this code, including: 

  • Failed spark plugs 
  • Broken or damaged ignition coils  
  • Broken or damaged plug wires 
  • Broken or damaged fuel injectors 
  • Engine vacuum leakage 
  • Broken exhaust gas recirculation system   
  • Not enough fuel pressure
  • Malfunctioning catalytic converter 

If you encounter this code, I recommend taking your Can-Am Maverick to a mechanic immediately. They will diagnose the code by inspecting the electrical components of your vehicle, after which they will perform any necessary repairs. 

5. P0562

This fault code relates to the voltage of your vehicle. If there is a sudden drop in your voltage supply, the power control module will generate this code to alert you of the problem. For the module to generate the code, the voltage level has to drop below 10.0 volts for more than a minute. Usually, the average voltage level is between 14.1 and 14.4 volts at idle (source).  

In addition to the code, the “Check Engine” light will be on if you’re having voltage issues. Other symptoms of a voltage problem include: 

  • Failed electric functions such as power steering
  • Degraded engine performance 
  • Unsuccessful attempts to turn on the engine 
  • Lower fuel efficiency than usual 
  • Problems when shifting  

You should take this P0562 code seriously, as it indicates a serious electrical problem that could cause further damage if left unsolved. All of the electrical components in your vehicle need a power source to work properly (or at all), and if there isn’t enough voltage, they won’t get the power they need and will stop working. 

Usually, this code indicates that the alternator or voltage regulator is broken or damaged. However, there are other potential causes, which include: 

  • Battery drain 
  • Faulty wiring 
  • A broken battery cable 
  • A broken battery 
  • A broken powertrain control module 

To fix the problem and clear the code, you or a mechanic must replace the broken alternator or voltage regulator, replace any bad batteries or cables, and repair faulty wiring. Failure to address this issue right away will result in engine damage.
