What it means

P1853 on a Saturn means the transmission control module has detected a high voltage on the brake band apply solenoid circuit. The module saw a voltage higher than expected for the commanded state, which usually points to an open circuit, a short to voltage or a fault in the solenoid or its driver. The exact solenoid layout and circuit depend on the transmission fitted, so check the model-specific wiring information.

Symptoms

  • Gearbox warning light or check engine light on
  • Transmission stuck in one gear (limp-home mode)
  • Harsh, delayed or missing gear changes
  • No engagement or slipping in certain gears
  • Poor fuel economy or reduced performance

Possible causes

  • Open circuit or high resistance in the solenoid wiring or connector (corroded, loose or pushed-back pins)likely
  • Faulty brake band apply solenoid (open winding)likely
  • Damaged internal transmission wiring harness or pass-through connector, possibly with fluid contaminationpossible
  • Wiring shorted to a voltage supplypossible
  • Low or contaminated transmission fluid affecting the valve body or solenoidpossible
  • Faulty transmission control module driver circuitrare

How to diagnose

  1. Read all stored and pending codes and note the freeze frame data, including vehicle speed, gear and battery voltage
  2. Check the battery condition and charging voltage, as low or unstable supply can upset solenoid circuits
  3. Inspect the transmission fluid level, condition and smell, and look for leaks around the connector
  4. Visually inspect the transmission wiring and connectors for damage, corrosion, water or fluid ingress and bent or spread pins
  5. Using the wiring diagram for the specific model and transmission, test the solenoid circuit for supply voltage, continuity and shorts to voltage or ground
  6. Measure the solenoid winding resistance and compare it with the manufacturer specification
  7. Command the solenoid with a scan tool, if supported, and watch for the expected response
  8. If the wiring and solenoid test good, check the control module power, grounds and driver output before considering the module

How to fix

  • Repair or replace damaged wiring, terminals or connectors, and clean up any corrosion
  • Replace the brake band apply solenoid if its resistance or operation is out of specification
  • Replace the internal wiring harness or pass-through connector if it is faulty or contaminated
  • Correct the transmission fluid level, or service the fluid and filter where the condition calls for it
  • Repair or replace the transmission control module only after the wiring and solenoid are confirmed good, and then carry out any required programming or adaptation

Can I keep driving?

Medium severity

The car can usually be driven short distances, but expect limp-home behaviour and poor shifting that can stress the transmission. Get it checked soon and avoid heavy loads or long journeys.
