Question about 2005 Chevrolet Corvette
My car would suddenly stop and make a horrible noise. I could only drive 5 mph. Service Active Handling light came on. I took it to dealership the said they could not recreate the problem and there are No CURRENT codes for diagnostics. There are TWO codes in HISTORY that raise a red flag :C004 R/F Sensor Fault and C0035 L/F Sensor Fault . The others are steering C0710 , DRP C0281, and C0252 VSES. I took it back to the dealership today and asked them to check speed sensors wiring harness. They found nothing wrong. Should i replace both hubs?
Try another dealer-- they chased you with intention to resolve
I don't have the reference material to give you any answer- but
they obviously didn't work those codes,old stored enhanced data
To go 5 mph-- you went into failsafe of some type
My Corvette days are in 1965 Those I have done frame up,

Number 5 cylinder may have clogged fuel injector. O2 sensor can be replaced on exhaust pipe. EGR valve can also be replaced. good luck

SOURCE: KNOCK SENSOR KEEP GOING OUT
Make sure you are not over torquing it. if you screw it in to much, it will give false readings and if it is not screwed in enough, it will also give false readings.
There's a delicate balance to be known and, if this sensor is over torqued or, not torqued enough, it will malfunction.

before changing the hub check the abs connection-- the sensor wire connection clips onto the spindle-- a lot of times the connector comes loose or becomes disconnected from the clip by road debris or during a brake job the connector and clip are part of the abs circuit and causes an abs/trac check light-- if the connector is good- and the sensor is bad yes replacing the hub will fix ur problem the abs is integrated into the hub assembly

Tips for a great answer:
1 Ensure that fuel filler cap is fully closed (minimum three clicks).
2 Fuel level > 30% and < 85%.
3 Using WDS scanner perform ECM DTC Clear (even if no DTCs are flagged).
4 Drive vehicle for a minimum of 2 minutes, and until engine is at normal operating temperature.
5 Using WDS, ensure that the EVAP Canister Purge Valve is operating by observing "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE". If the valve is not
active, ECM adaptions have not been learned. Conduct a "green ECM" Drive Cycle as described in Technical Service Bulletin.
6 Drive vehicle to the road where the EVAP System Drive Cycle will be conducted. Stop vehicle and switch OFF the ignition. Leave ignition OFF for 30 seconds,
then restart the engine.
7 Accelerate briskly to 80 km/h (50 mph) ensuring that the engine speed reaches a minimum of 3500 rpm for a minimum of 5 seconds.
8 (0.040 inch EVAP Test) View WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER CLOSE VALVE - VAPOR RECOVERY SYSTEM", and
FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". Avoiding high engine loads, drive the vehicle steadily between 65 km/h (40 mph) and 100 km/h (60
mph). Avoid driving conditions that will produce excessive fuel movement. WDS should give an indication that the test is active (it may take up to 30 minutes
before the test will initialize). When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.
9 (0.020 inch EVAP Test) Continue driving vehicle as explained in Step 8 for an additional 10 minutes.
10 Gently coast the vehicle to a stop. Allow the engine to idle for 2 minutes and view WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER
CLOSE VALVE - VAPOR RECOVERY SYSTEM", and FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". WDS should give an indication that the test is
active. When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.
11 If the 0.020 inch EVAP Test is not activated, the purge system vapor concentration may be too great. To reduce the vapor concentration proceed as follows:
12 Drive the vehicle for an additional 30 minutes avoiding driving conditions that will produce excessive fuel movement. Repeat Step 10. If the 0.020 inch EVAP
Test is still not activated, repeat the Drive Cycle from Step 6.
13 Using WDS, check for and clear flagged DTCs
