What Does P1583 Mean?
This code indicates the electronic throttle monitor has disabled the cruise control system due to a detected fault. The PCM continuously monitors throttle control integrity, and when it detects a condition that could compromise safe cruise operation—such as a throttle position discrepancy or throttle motor issue—it disables cruise as a protective measure. The vehicle may otherwise operate normally, but cruise control will remain inoperative until the underlying issue is resolved.
Common Causes
30%
Underlying electronic throttle body malfunction triggering cruise disable
25%
Throttle position sensor signal out of expected range
20%
Accelerator pedal position sensor disagreement
15%
Wiring fault in the throttle control or cruise control circuit
10%
PCM software issue or calibration requiring reflash
Diagnostic Steps
1
Scan for all stored DTCs; this code is typically secondary to another ETC fault—identify and address the primary code first.
2
Monitor live data for throttle position sensor 1 and 2 values, APP sensor 1 and 2 values, and commanded vs. actual throttle position.
3
Inspect the electronic throttle body connector and wiring for damage, corrosion, or loose connections.
4
Check for any aftermarket throttle controllers, tuners, or modifications that may interfere with the ETC system.
5
Address the root ETC fault, clear codes, and verify cruise control operation returns during a road test.

The most common cause of P1583 (Electronic Throttle Monitor Cruise Disable) is: Underlying electronic throttle body malfunction triggering cruise disable
Typical repair costs for P1583 range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cruise control is disabled as a safety measure. The underlying throttle fault may also lead to reduced power mode if it worsens. Loss of cruise on long highway trips increases driver fatigue.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1583 to identify the root cause.
