Saturn Compressor AC Line Update

Over the years there are updates to parts just like thereare to car models. For every model year that a vehicle is in production thereare small changes that are more than skin deep. The AC compressor just like other automotive AC parts may change as the years go by. Sometimes a car company goes under andthe aftermarket has to take over the production of the replacement parts. Inthe case of Saturn that is exactly what happened, when the company closed itsdoors it left many of its vehicles owners out in the cold when it came toparts. Maybe out in the cold is the wrong term to use, out in the heat isbetter since the OEM AC compressor was no longer available the aftermarket didwhat it could.

The solution to the lack of supply was to find a compressorthat bolted into the same location as the original Saturn compressor. This isnice in theory but the problem arose when a compressor was found, the compressorcould bolt on but the AC lines would not hook up. The solution was found injust changing them out and sending the update out whenever a Saturn L series orVue compressor was sold.

Each one of the replacement compressors was sold with a setof the high and low side ac lines what could be easily swapped into the system.This simplistic fix is a great example of how the aftermarket is not just abunch of cheap parts but more a community of vendors who are working to createa market for anything that has a need.

What is a Throttle Position Sensor?

In order for your car to work properly everything must beworking in prime condition.  Fromsomething as big as a diesel turbo charger to something as small as a throttleposition sensor, if one thing is malfunctioning your car will feel theeffects.  We all know what car parts suchas an AC Compressor does, but a lot of us can get confused when we start totalk about all these sensors.  I thoughtI would help you out a little bit and explain what a one of these sensors does.

Present day vehicles have an assortment of diverse sensors. Whenit comes to these sensors the key is “knowledge is power.”  The sensors supply the knowledge to the computer so that the computer knows how much power needs to be out. One such sensoris the Throttle Position Sensor.  Thislittle guy is located on the intake butterfly on internal combustion engines.  The throttle position sensor is apotentiometer that reports to the computer in regards to how open the throttleis.  This valuable info combined withdata from different sensors is used by the ECU to determine the correct fuel amount,ignition timing, and other important tasks. In turbocharged vehicles, the throttle position sensor’s cherishedinformation assists the wastegate for better car performance.

A malfunctioning Throttle Position Sensor means that thecomputer is not getting the correct information it needs to work properly.  This means the computer, the brain of yourcar, has lost a lot of its brain cells. Your car may start to jerk, suddenly stall, and hesitate whileaccelerating, and the fuel economy will plummet.  So, make sure your brain is getting the rightinformation so you’re not blowing a bunch of cash at the gas station.  If your Throttle Position Sensor is brokenfix it immediately.
