P1416 - Secondary Air Injection (AIR) system Bank 2
1416 means that you are running lean while the smog pump is on.
It could also be likely the vacswitch on the smog pump is the causes.

1995 GMC Jimmy P0172, P0300, and P1406


Code 172 is for the fuel system being too rich on bank one.
Code 300 is for a random miss, and code 1406 is for a problem with the EGR valve or sensor.
Each component would need to be tested.

2001 gmc jimmy po171 lean bank code what could be the fix is it a possable o2 sensor


More than likely bank 1 sensor has a possible vacuum leak, or a lean misfire on that side of the bank.(lean misfire happens when gap of spark plug are exceed due to wear), As for the 02 sensor I agree that it is reporting the true engine condition on that side of the bank

Specifically sensor 3 bank 1 oxygen sensor 2000 GMC Jimmy 4.3L v-6 4wd


Skolruby, There are four different codes for bank1 sensor3 as i think you may have written it backwards. It goes as follows, code po143 ho2s circuit low voltage bank 1 sensor 3 po144 ho2s high voltage bank1 sensor 3 po146 ho2s circuit insufficient activity bank 1 sensor 3 po147 ho2s heater performance bank 1 sensor 3. If you are getting code 44 lean exhaust. or 45 rich exhaust, It will show up on an emmisions test witthout the check engine light on and fail. If you get code 45 you might have a csefi fuel meter leak, A common problem with this engine. It is hard to detect unless you dissesemble it and see raw gas by the plastic injector tubes. I have the same year and model jimmy. It took days on a diagnostic machine to shake it out, What a pain. good luck.

2000 gmc jimmy code po171 how to fix it


if i remember correctly that code is running lean on bank one (drivers side) of engine. normally the cause of this code is that the left side o2 sensor in front of the cat. converter is not reading correctly. to fix the problem i would first stop at a parts sore where they do free system scans to erify that is is that particular sensor. if that is the case then the solution is to replace it with a new one. hope this is of help, thanks

9141 does not exist I will assume it is DTC P0141 HO2S Heater Performance Bank 1 Sensor 2

The VCM has the capability to monitor this process by using the Heated Oxygen Sensor (HO2S Bank 1, Sensor 2). The HO2S (Bank 1, Sensor 2), located in the exhaust stream before the catalytic converter, produces an output signal which indicates the storage capacity of the catalyst; this in turn indicates the catalysts ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S signal will be far less active than the signal produced by the Heated Oxygen Sensor (Bank 1, Sensor 1).
When the HO2S temperature measures below 360°C (600°F), the sensor will not produce any voltage and will behave like an open circuit. This will result in an Open Loop operation.
The HO2S heater provides for a faster sensor warm-up which allows the sensor to become active in a shorter period of time and remain active during long extended idle. The DTC P0141 determines if the HO2S is functioning properly by checking the response time of the sensor. This DTC is a type B DTC.
