2003 Jetta TDI P0673 and OBD2 Code 00283 ABS - Front Left Wheel Speed Sensor Issue After Replacement

Model: 2003 Jetta TDI Fault Code: P0673 Posted: 2009-04-24 09:34

I'm currently experiencing two diagnostic trouble codes on my 2003 Jetta TDI: P0673 and OBD2 code 00283 (front left ABS wheel speed sensor). I have already replaced all the glow plugs and reset the system, which kept the check engine light off for about a month. However, the P0673 code has reappeared. Could this be due to a faulty wiring harness connecting the glow plugs? Additionally, I recently replaced the front left ABS wheel speed sensor (code 00283), but the code is returning after each reset. The issue persists even after multiple resets—could there be a problem with the sensor mounting, signal grounding, or another component in the ABS system?
