⚠️ Drivable, but... — Yes, but your anti-lock braking system will not work, so drive with extra caution, especially in slippery conditions.
Key Takeaways
  • A bad ABS sensor on your 1990 Del Del10002 will disable the anti-lock braking system and turn on the ABS warning light.
  • Replacement is simple for a DIYer, usually involving one bolt and an electrical connector, taking less than an hour.
  • Aftermarket 'Replacement' brand sensors are the only available option and are a cost-effective solution for this vehicle.
  • No recalls or specific Technical Service Bulletins (TSBs) are known for the ABS system on this model.
The Anti-lock Braking System (ABS) speed sensor is a critical part of your Del Del10002's safety system. It measures the rotational speed of each wheel and sends this information to the ABS control module. If the module detects that a wheel is about to lock up during braking, it rapidly pulses the brake pressure to that wheel, allowing you to maintain steering control. This data is also used by other vehicle systems, like traction control if equipped. In a 1990 vehicle, a single sensor on the rear differential might be used to monitor both rear wheels.

Symptoms of a Failing ABS Speed Sensor in a 1990 Del Del10002

When an ABS speed sensor fails, it will trigger clear warning signs. The most common symptom is the illumination of the ABS warning light 🎬 Watch this video to learn more about common sensor symptoms. on your dashboard. Because the sensor provides data for multiple systems, you might also see the traction control light come on. A faulty sensor can send incorrect data, leading to a loss of anti-lock braking function, which is most noticeable during hard braking situations. In some vehicles from this era, a bad rear ABS sensor can also cause an erratic speedometer or harsh automatic transmission shifting, as the sensor data is shared.

Choosing the Right Aftermarket Part

For a 1990 model, finding original equipment (OEM) parts is nearly impossible. The aftermarket is your primary source for a new ABS speed sensor. Since there are only a couple of options available, the choice is straightforward.

The "Replacement" brand is a standard aftermarket option. These parts are designed to be a direct-fit substitute for the original, meeting the basic form, fit, and function requirements. For a simple and common part like an ABS sensor on an older vehicle, a standard replacement is often a cost-effective and reliable solution. Quality is generally sufficient for daily driving needs, and they provide a significant cost saving over unavailable OEM parts.

Cost of a New ABS Speed Sensor for 1990 Del Del10002

Part Type Estimated Cost
New OEM Not Available
New Aftermarket (Replacement Brand) $24.72 - $31.84

Frequently Asked Questions (FAQ)

What are the most common reasons for ABS sensor failure on a Del Del10002?

Given its location near the wheels, the sensor is exposed to dirt, moisture, and road debris. Over time, this can lead to contamination or physical damage. Wiring can also become brittle and break from vibration and age, causing an internal short or open circuit.

Can I replace only the faulty ABS sensor?

Yes. You only need to replace the specific sensor that has failed. A diagnostic scan tool can read the fault codes from the ABS module to identify which wheel sensor is causing 🎬 See how to test and fix a faulty wheel speed sensor. the problem. If your vehicle uses a single rear sensor, diagnosis is even simpler.

Is replacing the ABS sensor a difficult job for a DIY mechanic?

No, this is generally an easy job. The sensor is typically held in place by a single bolt. 🎬 Follow this step-by-step guide to replacing your ABS sensor. After unplugging the electrical connector, you remove the bolt and pull the old sensor out. Sometimes they can be stuck due to rust, requiring gentle prying. The entire process can often be done in under an hour.

Do I need to reset the computer after installing a new sensor?

Usually, no. After you install the new sensor and start the vehicle, the ABS warning light should turn off by itself, sometimes after driving a short distance. If the light remains on, you can try disconnecting the negative battery terminal for about 15 minutes to clear the system's memory.
