What it means

P1569 on a Chrysler means the powertrain control module has seen the cruise control servo stroke (the position of the throttle-linked servo) at a high value while cruise control was not switched on. In other words, the servo is reporting movement or position that does not match a cruise-off condition. Exact servo type and how the fault is detected vary by model, year and engine, so check the model-specific service information.

Symptoms

  • Cruise control light or engine management light on
  • Cruise control not working or cutting out
  • Throttle feeling stiff, sticky or slow to return to idle
  • Unstable or raised idle speed
  • Cruise control engaging unexpectedly or surging (model dependent)

Possible causes

  • Cruise control servo or its position feedback faulty or stickinglikely
  • Damaged, chafed or corroded wiring or connector in the servo circuitlikely
  • Throttle cable or linkage binding, misadjusted or not returning fullypossible
  • Faulty brake or clutch switch giving the module a wrong cruise-disengage signalpossible
  • Vacuum leak or damaged vacuum line to a vacuum-operated servopossible
  • Fault inside the powertrain control module or an outdated calibrationrare

How to diagnose

  1. Read all stored and pending codes and note the freeze frame data, including whether other cruise, throttle or brake switch codes are present.
  2. Visually inspect the servo, throttle cable and linkage for damage, binding, fraying or incorrect adjustment, and check the throttle returns smoothly to idle.
  3. Inspect the servo wiring and connectors for chafing, water ingress, corrosion and loose pins.
  4. If the servo is vacuum operated, check the vacuum lines and fittings for splits, leaks and blockages.
  5. Check the brake and clutch switch operation and their signals using a scan tool live data display.
  6. Check the cruise control switch inputs and the servo position reading in live data with cruise off, comparing against the manufacturer's specification.
  7. Test the servo circuit for continuity, short circuits and supply/earth integrity following the model-specific wiring diagram.
  8. Check for relevant technical bulletins or calibration updates for the vehicle before considering the control module.

How to fix

  • Replace the cruise control servo if it is sticking or its position feedback is out of range.
  • Repair or replace damaged wiring, terminals or connectors in the servo circuit.
  • Free off, lubricate or replace the throttle cable and correct the linkage adjustment.
  • Replace a faulty brake or clutch switch.
  • Replace perished or leaking vacuum lines or fittings.
  • Update the control module calibration or replace the module only if testing confirms it is at fault.

Can I keep driving?

Low severity

The car can normally be driven while you book it in, though cruise control may not work. If the throttle sticks or fails to return to idle, stop driving and have it checked straight away.
