FAQ-ABS Sensor - GE7C4371YB
Q1: Which vehicle models is part number "GE7C4371YB" compatible with?
A: This part is specifically designed for the Mazda Protégé series, with detailed compatibility as follows:
Mazda Protégé: 2001-2003 model years
Mazda Protégé5: 2002-2003 model years
This is exactly the same vehicle models and years as the part "GE7C4372YB" we just analyzed.
Q2: What are its key physical specifications?
A: Its core installation specifications are: 1 rectangular male connector, 2 blade-type female terminals, a harness length of 980 mm (approx. 38.6 inches), and mounting at the Wheel location via 3 bolt holes. The most notable features are its extra-long 980 mm harness and the 3-bolt-hole mounting method.
Q3: What is the difference between it and "GE7C4372YB"? Are they interchangeable?
A: Although these two parts are compatible with the same vehicle models, they are two independent parts with completely different physical specifications and are NOT interchangeable. The core differences are:
Harness Length: GE7C4371YB is 980 mm; GE7C4372YB is 740 mm.
Number of Bolt Holes: GE7C4371YB has 3; GE7C4372YB has 4.
These differences indicate they likely correspond to different wheel positions on the vehicle (e.g., front left/front right, or front/rear) or different system configurations.
Q4: Why are there two different sensor part numbers for the same car model?
A: This is a common situation in automotive design, primarily to distinguish between different mounting positions or configurations:
1. Wheel Position Specific: The most common reason; sensors for the four wheels of a vehicle may not be identical. For example, front wheel sensors (with longer harnesses to accommodate steering movement) and rear wheel sensors may use different part numbers.
2. Model Year or Configuration Tweaks: Minor updates to components may have occurred during the 2001-2003 production run.
Therefore, even with the same model name, the specific part number used must be determined based on the physical old part.
Q5: How can I ensure I choose the correct part for my Protégé?
A: Facing two parts that fit the same model but have vastly different specifications, the only way to ensure correctness is to perform precise "old part matching":
1. Step 1 (Mandatory): Remove the faulty sensor from your vehicle.
2. Step 2 (Core): Verify its part number. If the old part shows "GE7C4371YB", order this one; if it shows "GE7C4372YB", order that one.
3. Step 3 (Auxiliary): Simultaneously observe the old part's harness length (approx. 980mm or 740mm) and number of bolt holes (3 or 4) for double confirmation.
Do not place an order based solely on the vehicle model name or year memory.
