MAF or O2?

Get the new codes. Anything else is just a shot in the dark.

Ill go and buy a reader and get the codes ASAP. I hope its something I can fix im tired of dealing with a shop and being out the car for a couple of days.

I stopped at Auto Zone and got my codes. Now Im concerned.

P0740- Torque converter/clutch or transmission

P1128- Unknown

P1130-Unknown

I have a 2001 Tip with 99K on the Odometer

I've called my local shop and Im taking in in tomorrow morning. I'm going to look up the codes when I get home shortly. I'm guessing this won't be an easy fix?!

Looks like P1128 and P1130 are the same errors I had before getting the seal fixed. Could this be a bad MAF? How is the P0740 related?

My 99' had a CEL with P1128 and P1130. It had a wicked hesitation around 2k from time to time that would jolt the car. MAF was bad.

Best bet dude instead of just throwing parts to it. Go to a reputable shop around town. Ask them to diagnosis it. If they say its the MAF,order it from ************************************************************ and you can swap it out on your own.

I had the 1128 and 1130 codes. Removed and cleaned the mass air flow with cleaner. Codes are gone and have stayed away for quite some time. Worth a try.

I'll give it a shot tonight. I'm still planning on taking it in tomorrow morning.

From Loren over on Renntech:

"P1128 Oxygen Sensing Adaptation, Idle Range, Bank 1 – Above Limit
P1130 Oxygen Sensing Adaptation, Idle Range, Bank 2 – Above Limit
Possible fault causes:
– Incorrect signal from MAF sensor
– Intake air system leaking
– Fuel pressure too low
– Volume supply of fuel pump too low
– Fuel injectors fouled
– Exhaust system leaking

Bottom Line - in most cases we are looking at an air leak or a bad MAF. If the MAF is bad then it is sending the wrong signal to the DME.

P0740 Torque converter clutch, excessive power consumption
This is a CAN bus reading that is sent to the instrument cluster. I've seen this often from wheel spin.
I would reset this one and see if it comes back under normal driving."

Disconnect the MAF and if the car runs better, clean or replace the MAF.
