Causes

Faulty steering column tilt position sensor (potentiometer or Hall-effect sensor)
Corroded, damaged or loose connector at the tilt sensor or wiring harness
Short to power, short to ground or open circuit in the sensor signal / reference / ground wires
Missing or incorrect reference voltage from control module
Mechanical binding or damage in the tilt mechanism preventing proper sensor movement
Intermittent module communication or software/calibration fault

Symptoms

Steering column tilt adjustment inoperative or behaves intermittently
Steering/column-related warning or message on instrument cluster
Storage of B1C33 and possibly related DTCs
Tilt position readout incorrect or does not change in live data
Possible limp/limited function of column adjustment

What to check

Read and record DTCs and freeze-frame data with a dealer-level or capable OBD-II scanner; check for related codes
Check live data/stream for steering column tilt position while operating the tilt control
Visually inspect connectors and wiring at the tilt sensor and under dash/steering column for damage, corrosion or water
Check fuses and power/ground to associated modules
Back-probe the sensor connector and measure reference voltage, ground continuity and signal while moving the tilt
Wiggle test wiring and connectors while observing live data for intermittent changes

Signal parameters

Typical sensor circuit: three wires — reference voltage (approximately 5 V), signal output (varies with tilt), and ground
Expected signal: smooth, continuously variable voltage change with tilt movement (commonly ~0.5–4.5 V range for a potentiometer-type sensor)
Some systems use a Hall-effect sensor or digital PWM; signal should vary continuously and without dropouts as column moves
No sudden jumps, open circuit (OL), short to battery voltage, or short to ground should be present on the signal line

Diagnostic algorithm

Retrieve and record all stored DTCs including related modules; note freeze frame and current live data for tilt position.
Attempt to re-create the fault: operate tilt through full travel while watching live sensor value and note behavior.
Visually inspect tilt sensor connector and wiring for corrosion, bent pins, damage or water entry; repair as needed.
With ignition ON (engine off) back-probe connector: confirm reference voltage (~5 V) and ground continuity; if missing, trace to module/fuse.
Measure signal voltage while moving the tilt mechanism. Look for smooth change in voltage. If signal is open, shorted or jumps, suspect wiring or sensor.
If wiring and power/ground are good, disconnect sensor and measure its internal resistance (if specified) or replace with a known-good sensor per workshop procedures.
Check for mechanical binding in the tilt mechanism; free or repair the mechanism before replacing sensor.
Repair or replace damaged wiring/connector or sensor as required. If module communication or programming is suspected, consult manufacturer service information for module re-flash or calibration steps.
After repair, clear codes, perform calibration or adaptation procedure if required, operate tilt through full range and confirm stable live data and no recurrence of code during road/test station verification.
Safety note: steering column contains SRS components. Follow manufacturer procedures to disable the airbag system and battery isolation precautions before disassembly.

Likely causes

Damaged or loose connector at the tilt position sensor
Open or shorted signal wire between sensor and module
Worn or failed tilt position sensor
Mechanical binding in tilt assembly preventing correct sensor output

Fault status

⚠️ Status

Steering column tilt feedback signal missing, invalid or intermittent — tilt position sensor/circuit fault detected.
