Just got a tune... For h/c. The car has the and light on and the traction control has not been working. Took it to scan it at autozone after the check engine light went on and it showed a p0102. I cleared it and now it doesn't want to start. Also I had removed the rear end if that helps.

 

Insert (The car has the abs light on*)

 

Try unhooking the negative terminal. It'll "reboot" the car. I've had to do this a couple of times over the years.

Also make sure the MAP sensor didn't fall out our the wires come loose.

 

P0102 OBD-II Trouble Code
Technical Description

Mass Air Flow (MAF) Circuit Low Input
What does that mean?

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.
Symptoms

You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.
Causes

A code P0102 may mean that one or more of the following has happened:

The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)

Possible Solutions

The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.

 

I unhooked it ten mins and put back on did it again 10 ago, how long should I wait?

 

Don't have to wait long, particularly if you have any sort of light on.

You'll have to re-index your windows by putting them up and holding the button for 30 seconds or so BTW.

When you get it running you'll need to go back to the tuner to have him adjust the MAF again.

 

Also the powersteering belt was squealing

 

Nothing unplugged the mag and plug it again, it just turns over perfectly and shuts off... Pretty much vrooom and off

 

Maf*

 

You might have the balancer backing out. The belt shouldn't ever make noise.

Unfortunately it happens sometimes after cam jobs if it's not torqued properly and it's a very specific procedure. Usually accompanied by an oil leak.

 

Can you keep it running with the gas pedal?

Might want to take the MAF out and clean it since Autozone has maf cleaner in a can.

 

No leaks, the car ran good yesterday, took it for a spirited run around the mountains. Should I just give up and call a tow truck?

 

Have AAA drop it off at your tuner.

 

Clean the maf first.

Maybe if you ask nice they will let you borrow a maf from stock and try it (if they stock those).

 

I have that spray at home I'm getting it brought here. Guys I have bad luck I already used my long range AAA tow when it sent it to the shop for a bad crank sensor harness wire. I'll have to tow it to my local mechanic

 

Got an iPhone? Can you video the startup procedure so we can see it? If you email it to me at joegut at gmail dot com I'll post up here from youtube if you don't know how to do that on your phone.


Did you take the maf out? Did you by chance get some oil or junk on it?

 

It's alive!!!!! Thanks guys I cleaned the Maf and it started

 

Great news. What was on it?

If you have a K&N filter, perhaps the shop over oiled it. Better take it out and check.

 

Its a callaway. Im not sure what it had, I just removed the snorkel of the intake and sprayed maf cleaner in there since its freezing cold tonight lol. Probably dust as the car sat for a while before getting a tune. The car bucks a little when you intially gets on the gas but no check engine light at least for the 5 mile ride back home. Im wondering why the abs doesnt light doesnt reflect a code on the scanner. I was told that I had to set up the sensor when I reinstalled the craddle which i didnt so I know the problem and lack of traction control are probably related to that

Guys I want to thank you again. Good and quick help. Ill post my dyno sheet from the tuning now
