SOURCE: 2001 pontiac aztek egr vavle replacement

Hello. I used to work in a GM dealer. It is seldom the EGR valve that is the problem. If it is code P1404, the problem is a PCM calibration. Take it to a local dealer and they can reflash the PCM. If you want to get technical about it, the PCM is and emission control device and should be covered by warranty for 8 years or 80,000 miles.

SOURCE: how many heated oxygen sensors are on a 2001

You have 2 oxygen sensors, and they are mounted in the exhaust, one before and one after the catalytic converter. I am pretty sure the upstream one is threaded into the exhaust manifold, and is easy to find.

Where is O2 oxygen sensor Bank 1 sensor 2 on Pontiac Atzec.


The sensor two is the one located after the catalytic converter. While sensor one is always the O2 sensor located on the engine side.

Bankone refer to the sensor located in line with cylinder number one (theone that is sparking first i order). The firing order on Pontiac Atzec is as follows:

on the 4 Cylinder engine : 1-3-4-2

on the 6 Cylider version : 1-6-5-4-3-2,

This means that the cylindernumber one is located on the left hand side.

See the diagram below explaining how to access sensor two. The protective cover is not present on all models:


Note: before replacing the O2 sensor (lambda sensor) ensure that the problem is not wiring or connector.

Replaced cam sensor,oxygen sensor, egr vavle, when normal operating temp vehicle dies at stop signs and has jerking and sputtering when accelerating

If these symptoms only start after vehicle warms up, possible coolant temperature sensor. I would suggest having the sensor data scanned by a shop to monitor sensor operation to see if one is out of range before replacing any unecessary parts.

Pontiac aztek diy repairs

Yes. You would need a slotted socket that you can buy from AutoZone or Advanced Auto. They are pretty much standard sized. The trick is where it's located.

Had body control module replaced on 2001 pontiac aztek now the check engine light is on constant. codes indicate it could be a map sensor or an oxygen sensor is there a testing method for these and how do...

There are ways to test anything on any vehicle

That can only be done with knowledge,scan tools,
oscilloscopes,& vehicle reference material, such as
Alldata or you having all the factory service manuals

You can not work on todays vehicles by changing
parts, without doing any testing
