Hi there.... This sounds like an oxygen sensor has fail for bank 1. you can try rep;pacing the sensor and see what happens. the oxygen sesor is located on the exhaust in front of you catalytic converter. There should be two ( one one either pipe coming form the engine). If I remember the santa fe correctly , Bank 1 is the passenger side bank of the engine. Hope this helps you out

2008 uplander code p0172 bank 1 fuel to rich

I recommend having a shop take a look at it. It could just be the O2 sensor, or you really could have an injector putting too much fuel in one cylinder. A mechanic would watch the data stream coming from the sensor on a scanner to judge if the sensor is working or not.

I have dodge grand caravan sport the check engine is on the code is P0172 say sistem too reach bank 1

code p0172 refers to system too rich bank 1===causes --intake blocked (air filter) EVAP canister purge valve---fuel pressure---EGR system--injectors--HO2S (oxygen sensor). The first thing to check would be the oxygen sensor and air filter. Then check the fuel pressure in the fuel manifold to check for fuel pump/filter/ pressure relief valve that may be causing an injector fault

Hello, I have 2001 Pt Cruiser LE engine Code B 2.4l 206000miles: Problem Is extreme Hesitation, and in Park you can try Rev the engine but stall or kills the rev. PCM code p 0172 hO2 sensor I know, a...

A rich codes is hard to get. Something is restricting the airflow or you have something wrong with the fuel control. Check the air filter and if it is good. I would wonder if you have a leaking fuel injector. Do you know how to do a cylinder drop test? How well does it idle? Does it smell of raw fuel at idle? Is it hard to start after sitting?

2000 trooper starts and idles fine, but when i put it in gear and give it gas it barely moves and the rpms drop. Also, when i disconnect the spark plugs on the right side the engines continues running the...

WELL WHAT ENGINE HAVE YOU GOT I know it must be either a V6 OR V8 and if the right hand bank of either 3 or 4 plugs leads are taken off and it still keeps the same and it dosent make any differance to the revs etc then it got to be a gasket on the inlet manifold on that head so that no petrol vapor is getting as it is sucking air only..
But what i carnt work out is how it run correctly on the Left hand bank only (IT CARNT)
There was a Army truck 1 tonner years ago that was a v8 and they had it to run on 1 bank of 4pistons {as a 4 cylinder engine} and after 150.000 miles they would take the old pistons out and fitted 4 more to the other bank and they kept running 100%.. but you havent got one of them sorry to tell you.. So let me know the answer to all above Ron
