yo,
What damage did the shop do to the sensor?
Without the ABS Amber light On during normal driving, there p[rob is No Coe that we can use for the diagnosis, but try;
4WABS Self Test for using 12 v. light or ABS Light & Test Connector Location; "Locate ABS Test Connector; install 12 v test light between Pins C and E; If no test light is used, ABS warning light will flash; jumper ABS Data Link Connector Pins B and E. 1. Note: If 12V test light is not available, the amber ABS warning light also flashes during this test. Locate test connector in the engine compartment and install 12V test light between Pins C and E. 2. With the ignition off, jumper Pin E to B. 3. Turn key to RUN position. 4. Remove jumper between Pins E and B after 5 seconds. 5. Count light flashes of test light or amber ABS warning light...All codes are 2 digits long. 3 to 6 seconds between digits in the same code. 15 seconds between codes. Probably want to run this test at least twice, to get the hang of reading the codes..." read more; - Miesk5 note use Steve83's process for more info
