Oxygen Sensor - Code P-0130
Howdy -
re: 2001 S-40, 150k miles on the clock If I drive slow, short trips to the store, etc. I frequently get the 130 code. It never happens when I consistently drive over 40 mph. My OBD reader Live Data will also show: Fuel Sys 1 OL-Fault Internet search says: OL = Open loop. When you start the car till it warms up it runs in the Open loop mode. Meaning it will not monitor the O2 sensors till the car engine warms up enough to get into Closed loop mode (i.e. monitor the air/fuel ratio based on the O2 sensor readings) It could be your OL = Open loop. When you start the car till it warms up it runs in the Open loop mode. Meaning it will not monitor the O2 sensors till the car engine warms up enough to get into Closed loop mode (i.e. monitor the air/fuel ratio based on the O2 sensor readings) It could be your engine coolant sensor is getting bad. Other than: engine coolant sensor any other suggestions ? Thanks in advance, Tom

Some O2 sensors have a heating element, maybe yours need replacing?
This would be my first instinct, as code PO130 relates to O2 sensor

Hey volvo again,
I just had the battery cables changed out due to car shutting off. Need to take a break from repairs for a while. Hope all is well. Tom

The lambda light kept coming on (I don't own a code reader), but I noticed it only came on if it idled for a few minutes. If I got in it, started and drove straight away at motorway speeds the lambda light stayed off. Turned out to be the throttle position sensor. From memory it wasnt expensive, so might be worth a punt. Worse comes to worst, you'll have a spare TPS lol. (my personal theory is the carbon track in the sensor gets worn from sitting in certain positions for years on end and so eventually passes no current (open circuit). When this happens, the CPU relies on other data from other sensors to take a "best guess" at what the throttle is doing. But this is mere speculation on my part.) |

Hey Canis
Thanks for posting. I only own a code reader cause my car has been like Christmas every week for 5+ years bright lights popping up for various reasons. 21 year old car, stuff happens. I live in the USA North Carolina. Fortunately, the state says cars 20+ years are not tested for environmental car issues like O2, Catalytic Converter, etc. So I can just watch the check engine light turn on and give it a raspberry. https://en.wikipedia.org/wiki/Blowing_a_raspberry Then when I get home, pull the code reader out of the glove box and clear the codes. It doesnt happen that often. I recently had both battery cables replaced, due to the car shutting off + hard to start. So maybe this will fix the O2 issue also. The new cables help the car to start with a lion's ROAR. Hope you are well and avoiding the crappy Covid. Cheers, Tom FWIW the throttle position sensor is $100+ here in the states.
