How to replace the O2 sensor in a 2005 PT Cruiser?
Re: How to replace the O2 sensor in a 2005 PT Cruiser? Your upstream o2 sensor is located behind motor and manifold and need an o2 senor socket and racket plus extension to remove and then your downstream 02 sensor is on the side of Cat convertor (drive side)and same process to remove and replace
Why does the Check Engine light come on on my PT Cruiser?
Oxygen sensors can change the way that your PT Cruiser’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
Can a bad O2 sensor cause a bad check engine light?
The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong). It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your PT Cruiser:
Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
What happens when the oxygen sensor goes bad in a PT Cruiser?
It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your PT Cruiser: More often than not, when an oxygen sensor in your PT Cruiser goes bad, it will throw a diagnostic trouble code.
