It’s a 2012 Honda Fit.
Originally my car was reading 4 different error codes. Those error codes were p0301-p0304, which were misfires detected within the cylinders.

I replaced the ignition coils and spark plugs thinking this would solve the problem.

Error codes P0301-P0304 stopped appearing, and I was able to drive normally for approximately 300 miles.

I then got the check engine light back on, and the traction control light. The car was then stuck in limp mode again. The new error codes were P0301 again and 83-11.

I am not sure what is wrong with the vehicle. I would appreciate any advice.

 

Did you check to see if the spark plugs were tight? You may be running into the issue in this thread.

Another possibility is maybe you routinely use questionable gasoline? I mean, maybe try using injector cleaning in the case that the injectors are fouled up.

 

My '11 Sport AT did same thing: CEL & VSA lights on but never went into 'limp mode'.

I'm going out on a limb here but it's rarely if ever the coil packs but almost always loose spark plugs.

Check them and report back. Thx

 

I checked the spark plugs, and the tightness wasn’t the issue. There was an additional code of P0201, for an open fuel injector circuit. I had the injector checked to see if it was still receiving power and it was. The car only has 41k miles, and when I start the engine I will get high revs. Limp mode kicks in almost Immediately.

 

I ended up testing the fuel injectors and it turns out on of them was bad. I replaced the injector but the p0201 code seems to be permanent. Does anyone know how to clear this code?

 

Have you tried disconnecting the battery for about 10-15 minutes and reconnecting it?

You can also go to a local parts store that checks codes for free and ask the person working to clear it.

 

One son had a VW Jetta that was burning up $1600 catalytic converters (welded into a sections of exhaust fore / aft) under warranty. They talked to Germany while it was on lift (I was with car whole day to reset the anti-alcohol interlock system that randomly called for a sample or it shuts the car off). I was with the car during any test drives too.

The point is that their computer reset process had the tech completely disconnect the battery and touch the two battery cable terminals together (AGAIN - NEITHER CABLE WAS ATTACHED TO THE BATTERY +/- DURING THIS PROCESS). Might be just what the dr ordered to reset everything.

 

I had CEL/VSA lights and limp mode due to a broken wire on the throttle body harness. Based on your codes, it may not be that particular harness but check the connectors/wires. May be as simple as fixing a broken 18 gauge wire. *Fingers crossed*

Bottom (gray) wire had completely pulled from the connector and threw the engine lights/limp mode.
