C0035 with plausibility failure

Hi, Love my 09 Outlook I bought with 66,000 miles..Drove 8 weeks and ABS light came on with traction service light. did a check and code C0035 came up. so I ordered 2 front sensors from Rock Auto.. cleaned the pads and replaced the sensors..at engine start up, lights go off but driving less than 1/4 mile ..light is back on. this time with the "plausibility failure" added with same C0035. The car came with 285 50R 20 size tires on it..this is not the size listed on the doors to come on this car. I also just replaced the tires and put on the same size that was on the car when I bought it...like I said I drove it for 8 weeks with no code problems. the ABS light stays on now..and it has switched to front wheel drive only (AWD off) ..I called my GM dealer and they tell me a sensor (or wiring)is still bad if the ABS light stays on at start up. I could understand that but the "plausibility failure" part has me stumped. Any help guys ..I had planned a road trip soon and don't want to start with problems.

Re: C0035 with plausibility failure

You mention you replaced the sensors...the wire sensors that run down to the back of the wheel hub and pick up signals from the hub? Usually this error means one of several things 1) the sensor that you replaced is bad 2) The round magnetic encoder ring on the back of the wheel hub is dirty. or 3) The encoder ring is no good and the wheel hub assembly needs to be replaced.

Do some searches on the board for your error code and you'll find quite a few threads on this. Assume you already know that C0035 is for the left front wheel. Not familiar with a "plausibility failure" first time I've heard of this.

Re: C0035 with plausibility failure

Yes replaced both front sensors for ABS and I did think that code indicated driverside front..also I cleaned pads on replacement.When I say "pads" I do mean the encoder rings..(knew bout the bulliten).the weird thing here is at start up after repairs..the light cleared until driving about 1/4 mile or less..then remained on ever since. what does that mean? the dealers say if the light does not clear at startup, then the sensor is bad.. I am going to put it on a lift this evening to recheck the connector and make sure it is locked and not loose.

The light coming on after a bit of driving is normal if the vehicle isn't getting any data from the hub wheel speed sensor.

Re: C0035 with plausibility failure

I put it on a rack to check it closer. The driver side encoder ring on sensor is buggered up. Will have to replace the Bering and check it out again... more to come.

Re: C0035 with plausibility failure

for others info.


On some 2007-2010 OUTLOOK; 2007-2011 Acadia; 2008-2011
Enclave, CTS/CTS-V; 2009-2011 Traverse;the
following DTCs or Symptom codes may be set: C0035, C0040,
C0045, C0050, with symptom bytes 18, 5A, 0F. The ABS, Service
Traction Control System, and/or Service StabiliTrak lights also
may be illuminated.
This condition may be
caused by single or multiple
pieces of ferrous
metallic debris stuck to
the wheel speed sensor
magnetic encoder ring.
Instead of a traditional
mechanical-type tooth
tone wheel, some new
model vehicles use a
wheel speed sensor tone
wheel made of a magnetized
nitrile rubber ring,
typically brown in color.
This magnetic encoder
ring is now part of the inboard
bearing hub assembly
The magnetic encoder consists of multiple North and South pole
pairs surrounding the outer circumference. When the magnetic
encoder ring rotates and passes by the wheel speed sensor head,
it generates a sine wave in the wheel speed sensor. The wheel
speed sensor converts an analog signal to a digital square wave,
and typical digital signal values switch between 7mA (Low) and
14mA (High) DC current.
Encoder Ring
Cleaning
Inspect and clean any
debris from the encoder
ring using the following
procedure. This inspection
and cleaning procedure is
supporting information to
with symptom bytes 18, 5A, 0F can be repaired by removing or
cleaning any accumulated debris on the magnetic encoder ring,
located on the inboard side of the bearing hub.
TIP: Most repairs can be
performed without replacement
of the bearing hub assembly or
wheel speed sensor. Be careful
not to damage the bearing outer
seal when brushing or cleaning
the magnetic encoder debris.
Do not use any type of magnetic
tool to remove the debris from
the bearing magnetic encoder.
An external magnet can damage
the encoder.
1. Based on the specific EBCM
Wheel Speed Sensor DTC
code, inspect the appropriate
corner magnetic encoder ring
for possible debris.
• C0035 Left Front Corner
• C0040 Right Front Corner
• C0045 Left Rear Corner
• C0050 Right Rear Corner
2. If debris is found, gently use a
dry nylon soft bristle brush to
remove the foreign debris from
the magnetic encoder ring. If
debris was removed, proceed
to step 3.
If debris still remains, wash the
encoder ring using a mild soap
detergent and wipe dry.
3. Connect a scan tool to the
vehicle. Turn on the ignition.
Clear the DTCs.
4. Perform vehicle diagnostic
repair verification procedure for DTC C0035-C0050. Refer to the
appropriate Service Information.
the SI wheel speed sensor
diagnostic mechanical
fault table. In most cases
the DTCs C0035-C0050

Re: C0035 with plausibility failure

OK Guys I have fixed this code and all is well.. When I had the ABS sensor fault code I bought two ABS sensors from Rock Auto..When my mechanic guy replaced them on the driver side the sensor was corroded and stuck in place.. He elected to remove it by drilling it out. Fine but he drilled too far and buggered up the sensor code pad on the Bering. That is the reason the code cleared on startup but when rolling the code set off again. I did not know it was buggered until at a later date I put it on a lift and examined the sensor pad with my finger tips while rotating the wheel. I could feel the spots on the pad. I ordered a new Moog Bering and replaced the whole thing.. Fixed her good.. Drove on a trip to the coast and back with no more ABS or AWD problems. It You find it necessary to drill out a old sensor.. Please measure the sensor height and mark your drill bit so you DO NOT over drill into the sensor pad mounted on the Bering. That little mistake cost me more than 350.00 dollars..
