Service Engine Soon

[FutureEcotecOwnerAgain]

I recently went to Auto Zone and they gave me the codes for the reasons my ses light keeps coming on. And here is what they were.

P0113 - IAT Sensor 1 Circuit High Input
P1133 - Manual Control - Fuel Air Metering
P0130 - O2 Sensor Circuit Malfunction ( Bank 1 Sensor 1 )

So if anyone has any good information about this please reply back because I'm not trying to pay a crap load of money for this unless I have too.

are you already out of warranty?

You could start with the IAT sensor. Its very easy to replace and its cheap. It could be bad which is causing all of the other codes. The P/N is: 12160244. Should run you about $17 from the dealer. It is in the air duct from the air cleaner.

I believe 0130 is the upstream O2. Probably an easy fix on a 2.2L but can't say for sure.

It's just a bolt, with a plug in you header

Never heard of the other one could be the MAF :unsure:

Ecotec's don't have a MAF. They have a MAP and IAT sensor, but no MAF sensor. Also they don't have an EGR system..Thought that was kind of strange.

O I didn't know,

Never looked at a Ecotec up close

[merlot566jka]

it does have an egr...its built into the header and head. its not external...fyi

Nope it don't......This is from GM

"To help meet emission standards, Ecotec's engine management system computer precisely controls the ignition and fuel injection based on feedback from the two oxygen sensors and handles on-board diagnostics.The exhaust outlet architecture, along with the control system, in most cases enables the Ecotec to meet or exceed the current emission standards, without the use of Exhaust Gas Recirculation (EGR) or Air Injection (AIR). The rear facing exhaust results in a short distance to the catalytic converter for quick catalyst light off on cold starts. Other features like minimum gap platinum-tipped spark plugs and a 3-millimeter top ring land piston design also help to reduce the hydrocarbon (HC) emissions."

OS1S1 is the upstream oxygen sensor located right on your exhaust downpipe. Dealer cost is about $123.59.

Before buying this sensor check to be sure your Intake Air Temperature(IAT) Sensor is ok first or the same thing will keep appearing. PM me with your Email and I'll send you a scanned copy of the diagonstic, troubleshooter, and correction.

FWIW,

If you have less than 80K miles those parts are still under emmisions warranty. Click here (http://www.epa.gov/obd/warranties.htm#1) a little down the page under "EMISSION CONTROL PARTS". but, Its probably easier just to change the iat sensor and hope that's it, instead of messing with the dealer :beerchug:
