Trouble Code P1151 means:Lack of HO2S bank 2,sensor 1 switches,sensor indicates lean
In a 2002 Saturn L300, the fuse that controls the heated oxygen sensor (HO2S) circuit is typically located in the under-hood fuse box. You can find the fuse box near the battery, and the specific fuse for the HO2S circuit is usually labeled in the fuse box cover. It’s advisable to consult the owner's manual for the exact fuse number and its location for accurate identification.
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.
