Trouble Code P1151 means:Lack of HO2S bank 2,sensor 1 switches,sensor indicates lean
P2195 - stall at idle after a cold start P2195 - front HO2S signal stuck lean P2195 - may be displayed in case of " stuck rich "
It has 2 ho2s sensors. One is upstream from the catylitic converter between the exhaust manifold and the cat. The other is downstream from the converter between in and the exhaust pipe going to the muffler.
The HO2S (heated oxygen sensor) in the code P1153 would be located in the exhaust system directly behind the passenger side exhaust manifold. Best reached from under the vehicle for replacement.
They are Emission control measures to reduce smog. SFI siequential fuel injection, EGR exaust gas recirculation, TWC three-way-catalyst, HO2S Heated O2 Sensor
Trouble code P2195 means: Lack of HO2S-11 Switching, Sensor Indicates Lean
Trouble code P1131 means:Lack of HO2S bank 1,sensor 1 switches,sensor indicates lean
Trouble code P1147 means: HO2S-12 (Bank 1 Sensor 2) Rich Shift Monitoring (Bank 1)
You have 2 sensors 1 is located in front or back of the catalytic converter and one is located in front of the vehicle where the muffler is located. They call oxygen sensors.
There is no fuse. It means there is a problem in the catalyst moniter heater circuit bank #2, sensor #2. here is a brief description of why this code was set: During testing the HO2S Heaters are checked for opens/shorts and excessive current draw. The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Possible causes: Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM wiring. Damaged HO2S heater. Damaged PCM.
Technical DescriptionLack of HO2S-21 Switch, Sensor Indicates Lean What does that mean?A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. SymptomsYou will likely not notice any drivability problems. CausesA code P1151 may mean that one or more of the following has happened: Electrical:Short to VPWR in the harness or HO2SWater in the harness connectorOpen/shorted HO2S circuitCorrosion or poor mating terminals and wiringDamaged HO2SDamaged PCMFuel System:Excessive fuel pressure Leaking/contaminated fuel injectorsLeaking fuel pressure regulatorLow fuel pressure or running out of fuelVapor recovery systemInduction System:Air leaks after the MAFVacuum LeaksPCV system:Improperly seated engine oil dipstickEGR System:Leaking gasketStuck EGR valveLeaking diaphragm or EVRBase Engine:Oil overfillCam TimingCylinder compressionExhaust leaks before or near the HO2S(s)Possible SolutionsSee the above list of causes and go from there.
