Anyone want to tell me what these mean?

Key On Engine Off Test:
556 O,C Primary Fuel Pump failure
522 O Manual Lever Position (MLP) circuit open/transmission in gear

Key On Engine on Test:

538 R Insufficient RPM change (operator error) during Dynamic Response Check

I do not get this because I did not change anything during that test. Am I doing something wrong? I ran the test 3 times and got the same result.

 

Bump

 

This may sound funny but my brother had the same codes show up one day for no reason. He used a scanner to clear the codes, and they came back. He removed the cables from the battery and let it sit for over and hour to reset the ECM and everything was fine after that.

 

Strange, very strange. I removed the battery cables right after I pulled the codes, so maybe they'll just go away. I'll pull the codes tomorrow when I get off work.

 

522: you have to hold down the clutch during the KOEO test.

538: you have to "goose" it (quickly to full throttle and back) right after the engine code is output.

The fuel pump code means the fuel pump lost power at some point.

 

Thanks for the reply,
I took the battery cable off last night and when I pulled the codes this morning. I got...

KOER test:
213 R SPOUT(Spark Out) circuit open

What exactly is that supposed to mean?

 

spout connector in wire harness near distributor is unplugged

 

What exactly does it look like? I cannot seem to find it.

 

Some spout connectors are near the distributor, and the others were right under the CC servo next the Ignition Control Module on the driver side close to the firewall.
Either way...It's going to be a connector that has two wires going to it and a grey plastic jumper that will be plugged into the end of it. If it's there then pull it out and make sure it's clean. Hope that helps.
