Forward Camera Obstruction Disables Cruise Control
What does TESLA-AP_W003 mean?
The TESLA-AP_W003 (Tesla Autopilot Controller (AP)) EV fault code means: Forward Camera Obstruction Disables Cruise Control. This is a moderate severity code.
Common Symptoms
- Touchscreen shows a gray cruise control icon with a message that traffic-aware cruise control is unavailable
- Autopilot and Autosteer are greyed out and cannot be engaged from the stalk or touchscreen
- A banner appears at the top of the screen reading 'Camera Blocked' or 'Cameras Degraded'
- The car drives normally under full manual control but refuses to engage any driver-assist features
- After rain or car wash, the warning clears on its own within a few minutes of driving at highway speed
- In freezing temperatures the warning appears first thing in the morning and does not clear until the windshield heats up
- Placing a parking permit sticker or registration tag near the rearview mirror causes the warning to appear permanently
Probable Causes (Ranked by Likelihood)
- Water droplets, ice, snow, or fog on the windshield directly in front of the forward camera cluster behind the rearview mirror Very Likely
- Dirt, road film, or bug splatter accumulated on the windshield in the camera field of view Very Likely
- Sticker, tint film, suction-cup mount, or other object placed on or near the windshield in the camera zone Likely
- Interior windshield fogging from high cabin humidity blocking the camera view from inside Likely
- Glare or direct low-angle sunlight overwhelming the forward camera sensor temporarily Possible
- Cracked or pitted windshield in the camera sweep area scattering light into the lens Possible
- Rare firmware or Autopilot ECU fault causing a false obstruction detection even with a clean windshield Less Likely
Step-by-Step Diagnostic Procedure
Check the windshield exterior in the zone directly behind the rearview mirror. This is roughly a 6-inch-wide band at the top center of the glass. Look for ice, snow, mud, or heavy water sheeting that has not cleared.
Check the windshield interior for fogging. Turn on the front defroster and set HVAC to fresh-air mode. Drive for 3-5 minutes and see if the warning clears on its own.
Inspect the windshield for stickers, registration tags, parking permits, toll transponders, or suction mounts placed anywhere in the top third of the glass. Even a transparent sticker can confuse the camera IR sensor.
If the windshield is clear, open the Tesla touchscreen service menu by long-pressing the brake pedal while holding both scroll wheel buttons for 10 seconds to trigger a soft reboot. After the reboot, check whether the code clears at speed above 25 mph.
Download Scan My Tesla with an OBDLink MX+ or Veepeak adapter and check the AP fault log. If AP_w003 is the only active fault and it clears after a reboot, the root cause was environmental and not a hardware failure.
Inspect the windshield under direct light for cracks, chips, deep pitting, or haze in the camera field of view. A windshield with a star crack even slightly inside that zone can trigger this code persistently.
If the code reappears immediately after a reboot on a clean, dry, unobstructed windshield, the forward camera module itself may have a calibration drift or hardware fault. At that point you need Tesla Toolbox 3 or a Tesla service appointment to run a camera diagnostic and recalibration cycle. This is not a DIY step.
Frequently Asked Questions
What does Tesla code AP_w003 mean?
It means the Autopilot system detected that one or more forward-facing cameras behind your rearview mirror are obstructed or producing a degraded image. The system disables traffic-aware cruise control and Autosteer as a safety measure until it can see clearly again.
Can I still drive my Tesla with AP_w003 active?
Yes, the car drives completely normally under manual control. You just cannot engage Autopilot, traffic-aware cruise control, or Autosteer until the obstruction clears. All other vehicle systems are unaffected.
Will this code go away on its own?
Very often yes. If rain, snow, ice, or fog triggered it, the code typically clears within a few minutes of driving once the windshield is clean and dry. If a sticker or damaged windshield is the cause, it will not clear until you fix the physical problem.
How much does it cost to fix AP_w003?
If cleaning the windshield or removing a sticker fixes it, the cost is zero. A cracked windshield replacement runs $400-$900 depending on model, plus a recalibration fee. A failed camera module is typically $600-$1,200 at an independent shop. Start with the free steps first since environmental causes are by far the most common.
