KOEO 111 and 334

KOER 314 311 536 632

Can anyone tell me what they mean? I have my air pump bypassed so thats probably some of them.

Do any of these mean the low speed fan isn't working, or the coolant temp sensor is bad? I am having cooling problems in the middle of winter!

Thanks,

Pete

111 = Pass Code
334 = EGR Valve Position Sensor - signal voltage higher than expected

314 & 311 = Thermactor Air System Problem - no operation during engine run self test

536 = Brake On-Off Switch failure or not activied during engine run self test

632 = Overdrive Switch - no switch action detected during engine run self test

What does 334 mean? Voltage higher than expected? Is that good or bad?

Where did you find these codes? Online?

Thanks,

Pete

That EGR code probably means your EGR valve is sticking open sometimes.

I would also like to know if codes 314/311, 536, and 632 are anything worry about.. And if they are hurting performance, and drivablity in any way.. becuase ive had these codes for a while, they come up everytime i scan.

No, those codes aren't hurting performance.
