error code 17, check engine light?

[Kenny]

Hi everyone, we finally got our Ranger on Friday. Went for a ride this afternoon, drove about 50 miles. Almost home when it acted funny and then the check engine and the transmission warning lights came on. We pulled off the road and turned off the Ranger. When I restarted it both lights were on so we drove it home very slow. Shut it off and waited. later when I started it the Trans light was out but the check engine light was and is still on. Will call dealer in morning and see what he says to do. Any ideas? Thanks, Kenny

It's hard to say what's going on, just like new cars today these damn things got more technology than they need. There's a good chance that "something" small occurred that caused it to throw the lights on and it's no big deal. Best bet is to have the dealer diagnose just in case. Hopefully he doesn't just disconnect it from to battery to reset it and send it back home and says let me know if it does it again.

According to Google........take it for what it's worth.
AI Overview

A Polaris Ranger XD error code 17, often appearing as part of the combined code 520344-17, indicates that the engine is running lean, meaning the air-fuel ratio is too high. Common causes include exhaust leaks, intake leaks, a faulty O2 sensor, low fuel pressure, or a clogged fuel filter. To troubleshoot, first check for obvious exhaust leaks and ensure your fuel filter is not clogged, as this is a frequent cause for this error. If these steps don't resolve the issue, inspect the O2 sensor and its wiring, and consider using a diagnostic scanner to clear the code and check for further clues.

Common Causes:

• Exhaust Leaks:
  Leaks in the exhaust system, especially before the O2 sensor, can introduce fresh air, making the sensor think it needs more fuel.
  
  
• Intake Leaks:
  Any air entering the system after the throttle body can cause the air-fuel mixture to become too lean.
  
  
• Faulty Oxygen (O2) Sensor:
  A failing O2 sensor can incorrectly detect a lean condition or send faulty signals.
  
  
• Low Fuel Pressure:
  Insufficient pressure in the fuel system can prevent proper fuel delivery, leading to a lean condition.
  
  
• Clogged Fuel Filter:
  A clogged fuel filter restricts fuel flow, which can cause a lean condition and overwork the fuel pump.
  

Troubleshooting Steps:

1. 1. Check for Leaks:
   Carefully inspect the exhaust system for any holes or cracks. You can sometimes feel for leaks with a running engine (briefly, as it will get hot).
   
   
2. 2. Inspect Fuel Filter:
   Determine if the fuel filter is clogged, as this is a very common cause for code 17.
   
   
3. 3. Examine the O2 Sensor:
   Check the O2 sensor's wiring and connector for any signs of damage or corrosion.
   
   
4. 4. Check Fuel Pressure:
   Use a pressure gauge to verify that fuel pressure is within the correct range (typically 55-60 psi).
   
   
5. 5. Reset the ECU:
   Try disconnecting the negative battery terminal for about 10 minutes to reset the Engine Control Unit (ECU) and clear the code.
   
   
6. 6. Seek Professional Help:
   If the issue persists, take your Ranger XD to a dealer or qualified technician, as they have specialized diagnostic tools and expertise to diagnose and repair the problem.

Thanks, Big Red, I will contact the dealer first thing this morning.

I took it to the dealer yesterday and when I unloaded the check engine light was still on. When the mechanic got in it the light was off. He came and told me this. I showed him a picture of the fault code, and he said nothing was stored. He took it for a drive and the light stayed off. It has the latest flash in it so he couldn't reflash it. He also told me it was in sport mode but I never put it in sport mode. Nothing else I could do so I brought it home.

That’s disappointing to hear. I was under the impression that all faults were stored. Maybe I’m wrong. Did he atleast explain or tell you what the fault code could be from your photo? Not sure what being in sport mode has to do with it. That’s the mode I’m in most of the time, unless I want to conserve some fuel, if I’m gonna be out for a long time.

The mode is easy to change accidently so I wouldn't be to worried about that. Hopefully it was just an electrical glitch but those sometimes have a history of showing up again later. Technology is a good thing until it ain't..........

Mine threw a transmission fault code & check engine light once for about 10 miles and went away. I'm curious about key cycles. I had a truck once that had the check engine light come on sporadically and would go away after 5 key cycles. Electrical gremlins are the worst.

Agreed, intermittent electrical issues are by far the worst issue in anything.
