Trouble code P0420 means:Catalyst system efficiency below threshold
Swap rear tires from right to left, see if the wobble changes sides. If the wobble changed sides you have a bent rim or a bad tire. If the wobble didn't change sides you have a bent axle or hub.
Yes, along with dozens of other things.
Cam sensor and/or crank sensor.
Yes.
I think that switches with bad grounds can burn up like that.
Could be a main engine relay problem.
A plugged transmission filter can cause your transmission to hesitate when you shift into drive. A collapsed vacuum hose can also cause the problem.
Subaru sucks. why the hell would you want a Subaru, especially the cheapest Subaru cause they all blow.
Yes, a 1994 Subaru Impreza requires a catalytic converter as part of its emissions control system. The catalytic converter helps reduce harmful emissions by converting harmful gases into less harmful substances before they are released into the atmosphere. If the catalytic converter is removed or malfunctioning, it can lead to increased emissions and may cause the vehicle to fail emissions testing. Additionally, it is illegal in many places to operate a vehicle without a functioning catalytic converter.
A code P0420 on a 2006 Honda Pilot indicates that the vehicle's onboard diagnostics have detected an issue with the catalytic converter's efficiency. This code typically means that the converter is not functioning as effectively as it should, which can be caused by a faulty catalytic converter, oxygen sensors, or exhaust leaks. It's important to diagnose the specific cause to ensure proper repairs, as ignoring this code can lead to increased emissions and potential damage to the engine.
Yes, the collision could have caused the AC issue in your Subaru Impreza. Damage to the rear passenger side might have affected components linked to the AC system, such as the refrigerant lines or electrical connections. Additionally, if the impact caused any frame misalignment, it could have indirectly affected the AC's performance. It's advisable to have a professional inspect the vehicle to determine the exact cause.
Diagnose is the correct spelling (to determine the cause).
