In the world of sports cars, Porsches are known to be among the most powerful and reputable brands. They are highly coveted by car enthusiasts worldwide due to their sleek designs, powerful engines, and high performance. Despite their reputation, Porsches can suffer from car troubles as well, one of them being a faulty engine speed sensor.
A broken engine speed sensor can negatively affect the performance of your Porsche. Consequently, the car’s performance is impaired, which can be very detrimental. To enjoy a captivating driving experience from your Porsche, you should go beyond the regular maintenance schedule and get acquainted with the causes or signs of a faulty speed sensor.
What are the symptoms of a bad speed sensor?
A speed sensor’s functionality can be gauged in several small ways. If any of these occur frequently, take your car to a reliable and experienced automotive expert.
- The Check Engine Light is Illuminated: It is possible for the powertrain control module to illuminate the check engine light on your vehicle for several reasons, including a faulty engine speed sensor. To confirm whether the error code indicates a malfunctioning engine speed sensor, you will need to connect your vehicle to an OBD-II scan tool.
- Unresponsive Torque Converter Clutch: Torque converter clutches are activated at preprogrammed speeds. Transmission torque converters cannot apply the clutch unless engine speed sensors provide accurate information about engine speed. As a result, the transmission may overheat, slipping will occur, and the fuel economy will be reduced.
- Cruise Control Not Engaging: The powertrain control module disables cruise control automatically if it is unable to get information from engine speed sensors. For your car to run at a constant speed, the system needs the sensor’s data.
- Inaccurate Speedometer Readings: Speedometers get info from engine speed sensors, so malfunctioning engines can cause erratic readings or no readings at all. You can continue to drive your Porsche without a working speedometer, but driving safely will be difficult if you do not know how fast you are moving.
- Problems with Transmission: Transmission control modules and powertrain control modules determine shift timing based on information relayed by the engine speed sensor. As a result, a malfunctioning speed sensor will affect automatic transmission Automatic transmission problems are often related to bad engine speed sensors. There may be a delay in shifting, hard shifts, and limited gear operation if the engine speed sensor is faulty.
Common Causes of an Engine Speed Sensor Failure
- Corroded Connection: There’s a problem with the electrical connections, which prevents the sensor from sending its information to the rest of the vehicle. It needs to be completely replaced to work properly again.
- Accumulation of dirt: It is inevitable for car parts to accumulate dirt and debris over time. It is normal for your speed sensor to produce no signal for a while, but it is very important that your car’s computer can still receive information from it. Filth prevents it from doing so.
- Broken Connection Cable: Your car’s speedometer is connected to the engine speed sensors by a cable. When the cable breaks, the sensor will no longer send out information for your car to process.
