P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1). You have a bad O2 Sensor. I dont know how your O2 sensors are labeled, but your local auto parts store should help you with that one. Good luck to you. Let me know if you have anymore questions.

Sincerely,

JC

1996 gmc sierra 5.7L what would cause engine codes p0102, p0108, p0121,p0300 at same time?


p0102 is MAF mass air flow , circuit low input. Try these to reset code by trying following.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Inspect for any air leaks near the MAF sensor. Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor. Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor.

Trouble code p0154


code p0154 refers to heated oxygen sensor (HO2S) 1 bank 2 -- no activity detected===causes --wiring---HO2S---= ECM
it also refers to oxygen sensor (O2S) --no activity detected--===causes --- wiring---O2S sensor---ECM. May be you did not replace the sensors causing the fault.

I have a 96 gmc sierra. The OBD reads trouble code p0154. No activity in bank 2 sensor 1. I replaced the O2 sensor. How will the check engine light go off? do i unplug the battery for a certain amount...


You need someone with a programmer to reset it. Auto Zone used to reset at no charge but now laws have changed in some states because dealers were taking cars with check engine lights to them to have reset so they could sell cars without having to actually fix them. Hope this helps ,Good luck

P0154 code and p01153


both codes point to the oxygen sensor on bank 2 sensor 1 ..
that would explain the rough running also .. the engine will default to a rich condition ...

p0154 indicates no activity on bank 2 sensor 1 oxygen sensor
p01153 is showing "low switching" for bank 2 sensor 1 oxygen sensor ...

there may be a wiring pigtail coming from the sensor. that plugs into another connector a few inches away .. check that connector for damage or corrosion .. if its ok then you likely need a new oxygen sensor ..

its not a good idea to continue driving with this condition since it will eventually damage the catilytic converter. that is probably getting very hot now with the extra load of fuel ..

Your sensors are reading correctly so leave them alone. What you have is a fuel delivery issue. Your MAF sensor is telling your engine to lean your fuel mixture. You need to remove and clean or replace (is better) the MAF. But first replace your PVC valve and clean your ERG valve.

Trouble codes P172 and P175 keep storing in Computor for my 1996 GMC Yukon


Check/replace air filter as well as the MAF sensor. The most likely cause is a dirty/bad MAF sensor often caused by a dirty air filter. Below is a list of possible solutions:
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect fuel lines for cracks, leaks, or pinches
  • Check the fuel pressure at the fuel rail
  • Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
  • Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

1996 GMC Sierra 1500 P0174, P0171,P0154, AND P0122


Tim,

Yes these codes are associated with the MAF Sensor. One can trip the others as well. I would try removing the MAF Sensor and cleaning it first (brake cleaner or contact cleaner), then if that doesnt work I'd chalk up the bucks for a new sensor.

1996 Ford Taurus Chugging MAF


Did you buy a Ford MAF sensor? There are some brands that are not reliable or accurate. Buy a Ford MAF sensor, if your mechanic has decided that the MAF is faulty. You may have a leaking fuel injector, bad coolant temp sensor,bad oxygen sensor,dirty air filter, clogged exhaust system.
