How much does it cost to fix P0573?

Most Chevy Cruze owners pay between $15 and $120 all-in, depending on whether the root cause is a sensor, wiring, or a higher-cost mechanical component. DIY fits the lower end of that range; dealer pricing pushes the upper end.

Will P0573 clear itself?

Only if the underlying fault was intermittent and hasn't recurred over several drive cycles. Permanent fault codes (PDTCs) require a successful drive cycle after the fix, even after a scan tool clear.

Can I just clear P0573 with a scan tool?

You can clear it, but the check engine light will return on the next drive cycle if the fault is still present. Clearing is also a bad idea before an emissions test — you'll fail readiness instead of failing the code.

Does P0573 cause an emissions test failure?

Yes. Any stored powertrain code that has illuminated the MIL is an automatic OBD-II inspection failure in every state that runs OBD-II emissions testing.

What Does P0573 Mean?

P0573 is a generic OBD-II diagnostic trouble code stored when the Chevy Cruze's control module detects cruise control / brake switch a circuit high. In plain English: The brake pedal position switch is reading stuck or out of range. Cruise won't engage, sometimes the shifter won't release from Park.

On the Chevy Cruze (2011–2019), this code falls under the Body / Switches group. It's not always catastrophic on its own — the value is in the diagnostic information it gives you. Treat P0573 as a starting point for testing, not a parts list.

Repair complexity is typically a 1/5 wrench rating, with parts-and-labor estimates ranging from $15 on the low end to about $120 for worst-case shop repairs including diagnostic fees.

Symptoms

Check engine light

Steady illumination after the code matures. Some Chevy models also store a freeze-frame snapshot.

Drivability change related to body / switches

May be subtle — owners often notice fuel economy, idle quality, or shift feel before they notice the light.

Possible related codes

Codes in the same system family often set together. Pull the full code list, not just the first one.

Emissions readiness failure

Vehicle will not pass an OBD-II emissions inspection while this code is stored.

Common Causes

1.Failed component within the Body system
45%
The most common single point of failure. Verify with a direct test — don't replace based on the code alone.
2.Wiring or connector fault
25%
Corroded pins, chafed insulation, and bad grounds mimic part failures. Check the harness before condemning a sensor or actuator.
3.Related upstream issue
20%
Other faults in the body / switches group can cascade and set P0573 as a downstream effect.
4.Software / calibration / TSB
10%
Check for an open Chevy technical service bulletin or PCM reflash before opening your wallet.

Step-by-Step Diagnosis

Pull all stored and pending codes

Connect an OBD-II scan tool and read every code in the powertrain module — not just P0573. Note the order they set in, and capture the freeze-frame data.

> SCAN /pcm/dtc
P0573  ACTIVE   (freeze-frame: RPM=1476, CTS=202°F)
MONITORS: O2=READY, CAT=READY, EVAP=NOT READY

Review freeze-frame and live data

The freeze-frame tells you the operating conditions when the code set (RPM, load, coolant temp, vehicle speed). Match it against live data while you try to reproduce the fault.

Pro TipIf the code sets cold and clears warm — or vice versa — that's a huge diagnostic shortcut.

Inspect the affected circuit visually

Before any electrical testing, pop the hood and follow the harness for the suspect component. You're looking for chafing, melted insulation, oil contamination at the connector, and corroded pins.

WarningMore than a third of intermittent sensor codes are wiring, not the sensor. A 10-minute inspection beats a $200 parts swap.

Test the suspect component directly

Use a DMM, scope, or bidirectional scan-tool command to test the primary suspect. Compare against the Chevy factory spec — generic values can be misleading.

Clear, drive, and recheck

Clear the code, complete a full drive cycle appropriate for this monitor, and rescan. If the code returns immediately, you're on the right path; if it stays gone, monitor for a week before declaring victory.

How to Fix It

DifficultyTime 2–3 hrs

Parts needed:

Primary replacement component for P0573 — approx $20
OE-grade connector / pigtail kit (if wiring is suspect) — approx $18
Dielectric grease — 3 oz tube — approx $6

Procedure:

Disconnect the negative battery terminal and wait 60 seconds.
Locate the primary component identified in your diagnosis.
Photograph the connector orientation and harness routing before removal.
Remove the failed component using the correct socket or specialty tool.
Install the new part, torquing fasteners to factory spec.
Reconnect the battery and clear the code with your scan tool.
Drive a full warm-up cycle and rescan to confirm the fix held.

FAQs

Yes, in most cases. P0573 on the Chevy Cruze is rated low severity. The check engine light will stay on until you clear the underlying issue, but day-to-day driving is normally fine.
