Please Help

05 mazda 3 hb 2.3L. CEL is on and car idles like sh#t and no acceleration. I hit a puddle last night and think that I sucked up some water. Cleaned and dried intake. Prom remains. Went to Advanced auto and had the diagnostics run...Error P0103 MAF or VAF A circuit High Input. Cleaned and dried MAF and connections and cleared the code. Prob still remains. Now I went and replaced the MAF and cleared the code again. Prob still remains with the same Code. Please any help is appreciated.

you need a new MAF i think its pretty obvious at this point

[protege_kid]

turn the vehicle off and then unplug the mass air flow sensor

then restart the vehicle and observe running conditions and get back to me

with it unplugged it stalled when originally started then when i started a second time it idled the same way...like sh#t.

alrightly this eliminates the sensor and related wiring from the list op possible problems because the vehicle would be forced into a "back up" strategy with the sensor unplugged and run better if the sensor was the issue

i am looking thru engine performance wiring diagrams and will se what i can find

when exactly did the drivablitiy problems begin? immediatly after hitting the puddle or the next time you started the vehicle
same question for the MIL, when you hit the puddle or next start or drive cycle

it bogged down about a 1/4 mile down the road after hitting the puddle and I am not sure what MIL means but the light also came on immediately if thats what you are asking. sorry

[protege_kid]

Mil is the malfunction indicator lamp which is displayed as the "check engine" light "service engine soon" or the engine symbol

k. I thought it was something like that. But yea it came on at the same time as the lack of acceleration...almost immediately.

pull back the cover on the wiring leading up to the maf, its very common for the wires to break, there is actaully a recall for some VIN numbers. not sure what your VIN is, but it would be something to look into. chances are if there is no difference wether its plugged in or not would lead me to believe its an electrical issue.

[dogwood]

yea that is what i think it is...I found it last night. Thanks for all the help

You Protege guys really know your stuff and really pull through for each other. I am continually impressed by your group. Almost makes me want a MSP...

compliments like this and the camraderie here is what keeps me on 24/7

ok ...now we have figured that its the broke wire on the connector to the Maf. The dealer is telling me that I need to buy a whole harness for 700, I cant buy just the clip and reconnect all the wires and all the auto stores dont sell it either. Is there a way to remove the broken piece of wire in my current clip so that I may just splice and reattach? I have tried pulling it out but to no avail.

[Captain KRM P5]

we used to be able to order connectors all the time and splice them in. i am sure if you search the internet for denso MAF connector you'll find something

There is a way you can depin the connector and resplice the wire. Let me see if I can find a picture for you.

that sounds great thanks. What kind of tool did you use to pop that pin?
thanks again for all the help

[RENE063]

You would need to find a really small flat head screwdriver. Almost like about the size you would need to fix the arms on sunglasses.

akaveli thanks again for all the help. spliced a new wired and attached it to the pin and presto we are back up and runnin.
