P0133: Oxygen Sensor Slow Response (Bank 1, Sensor 1)
What does the P0133 error code mean? The P0133 check engine diagnostic trouble code stands for "Oxygen Sensor Slow Response (Bank 1, Sensor 1)." The presence of this code indicates that the powertrain control module is no longer receiving signals from the oxygen sensor located on bank 1, sensor 1, quickly or frequently enough for the car to run optimally. This code may also be present on certain vehicles if there is a failure on bank 1, sensor 2. Why is this issue important? Oxygen sensors in your car are sensors able to detect the oxygen content in the exhaust gases leaving the car's engine. These gases are read and transmitted to the car's powertrain control module. From there, the powertrain control module uses this information to regulate the amount of fuel injected into the engine before the air and fuel mixture inside the engine's cylinder is ignited by the spark plugs. Usually, the result is a check engine light and other symptoms of an engine running poorly, like rough idling. Can I safely drive my car with this error code? Depending on the severity of the fault, it may be possible to drive with a P0133 code. However, the code does not always indicate the severity of the issue, and you should avoid driving if possible. The delayed sensor response may cause poor fuel economy and slight performance issues. More importantly, if the air-fuel mixture becomes too rich (meaning there's too much fuel and not enough air) or too lean (meaning the opposite), it could lead to engine misfires or damage. Common symptoms of the P0133 error code Illuminated check engine light Poor fuel economy Rough idling or hesitation Engine misfires Slower acceleration Black smoke from the exhaust How is the P0133 error code diagnosed?

Inspect the fuel system: Issues such as a clogged fuel injector or a faulty fuel pressure regulator can potentially impact the air-fuel mixture and trigger the error code. How is the P0133 error code repaired? Replace the affected oxygen sensor. Repair or replace damaged wiring and connectors associated with the O2 sensor. Fix vacuum leaks that could be affecting sensor readings. Clean or replace clogged fuel injectors to restore the correct fuel ratio.

P0505: Idle Control System Malfunction
What does the P0505 error code mean? The diagnostic trouble code P0505 means your car has detected an 'Idle Control System Malfunction.' The code triggers when the idle air control system goes bad in some way. There are a number of faults that can cause this code, including a vacuum leak. When your car's primary computer, or powertrain control module, detects a fault with the idle air control system, it will notify the driver via this diagnostic trouble code as well as a check engine light. Why is this issue important? The idle control system relies on an idle air control valve, typically located on or near your car's throttle body. It does what it says on the box: When your car idles, the throttle is closed, which limits the air supply heading into the engine. The engine does still need some air to keep going, however, and at the request of the car's powertrain control module, the idle control system will open a bypass air system that allows a little air into the engine to keep it running. This, too, can be adjusted by the system, allowing more or less air in as needed while the car is at idle. Can I safely drive my car with this error code? It could be possible to drive a short distance with a P0505 code, but it'll certainly be difficult if not downright hazardous. The faulty idling system will most likely present itself in the form of stalls, with your engine shutting down once it reaches an idle or when you stop hitting the gas pedal. It's best not to drive the car while this code is active — the car may end up stalled somewhere you don't want to be. Common symptoms of the P0505 error code Engine stalling at idle High or low idle speed Trouble starting your car The check engine light is on How is the P0505 error code diagnosed? Code verification : Use an OBD-II scanner to confirm the presence of the P0505 (or related) code. : Use an OBD-II scanner to confirm the presence of the P0505 (or related) code. Visual inspection : Inspect your engine's intake system for vacuum leaks, damaged hoses or loose connections. : Inspect your engine's intake system for vacuum leaks, damaged hoses or loose connections.

Check powertrain control module functionality: The mechanic will test the powertrain control module outputs to see if all physical components appear to be in working order. How is the P0505 error code repaired? Clean or replace the idle air control valve if clogged or faulty. Repair or replace damaged vacuum hoses or intake components. Fix or replace any corroded or broken wiring or connectors. Reprogram or replace the powertrain control module if it is found to be defective. Clear the code and test the vehicle to ensure symptoms are removed. Related reading On-board diagnostics (OBD-II) and diagnostic trouble codes are part of your car's self-diagnostic system.

More Than 46,000 Vehicles Recalled by Ford, Volvo, Nissan Over Safety Risks
Ford (F, Financials) recalled 37,823 vehicles, including certain 2020 to 2022 Escape, 2021 to 2023 Bronco Sport, and 2020 to 2022 Explorer models, multiple media outlets reporrted. Some of the vehicles may have been incorrectly repaired under previous recalls. Warning! GuruFocus has detected 4 Warning Signs with F. The fuel injector may crack in the Escape and Bronco Sport models, letting fuel leak into the engine. This makes the fire risk higher. It was discovered that the Powertrain Control Module software in these cars was not up to date, which would have reduced the risk. For Explorer cars, the recall is because of a broken rear axle fixing bolt that could let go of the driveshaft. It was also found that these units did not have the required software software update for the Powertrain Control Module will be given for free by Ford stores. Notice letters to the owners should be sent by April to a problem with the high-voltage battery, Volvo called back 7,483 plug-in hybrid cars of different types. The recall notice says that the battery could short-circuit when it is fully charged and stopped, which could start a fire. The 2020 to 2021 S90, the 2020 to 2022 S60, V60, XC60, and XC90, and the 2022 V90 are all impacted. People who own the cars are told not to charge them until the problem is fixed. The high-voltage battery part will be checked and replaced by the dealer, who will also update the software that monitors the battery. Emails will start going out on May (NSANY, Financials) recalled 1,430 cars, such as the 2025 Nissan Murano, Pathfinder, and INFINITI QX60, because they thought the front brake caliper parts might not be as strong as they should be and could break. Dealers will check the brakes and repair them if needed at no cost to the owners. Letters of notification will be sent out on May 9. This article first appeared on GuruFocus.
