Causes

  • Open or shorted wiring between TCM/ECM and the CVT solenoid
  • Poor connector contact (corrosion, bent pins, water intrusion)
  • Failed CVT shift/pressure control solenoid
  • Blown fuse or faulty relay in transmission control circuit
  • Internal transmission hydraulic fault affecting solenoid load
  • Faulty transmission control module (TCM/ECM) or software issue

Symptoms

  • Check Engine Light or AT/CVT warning lamp illuminated
  • Erratic shift behavior, harsh or delayed CVT response
  • Reduced engine power / limp mode or reduced shift range
  • Transmission slipping or unusual CVT belt/chain behavior
  • Stored transmission-related trouble codes

What to check

  • Scan for stored and pending codes; record freeze frame data
  • Inspect transmission and solenoid connectors for corrosion, damage, water
  • Check related fuses and relays for continuity and operation
  • Visually inspect wiring harness along routing for damage
  • Backprobe solenoid connector to measure reference voltage and ground while commanding
  • Measure solenoid coil resistance (unplugged) and compare to spec

Signal parameters

  • Coil resistance: expected low-ohm value (single to tens of ohms; compare to service spec)
  • Reference voltage/supply: approx. battery voltage when key ON (check spec)
  • Ground continuity: near 0 ohms to chassis ground
  • Control signal: PWM duty cycle/frequency from TCM when commanded (varies by model)
  • Command vs actual: TCM command and response should match within spec

Diagnostic algorithm

  1. Read and record DTCs and freeze frame data. Note MIL status and related transmission codes.
  2. Perform a visual inspection of the solenoid connector, wiring, harness routing and transmission case for fluid contamination or damage.
  3. Verify fuses/relays for the transmission control circuits; replace if faulty.
  4. With ignition OFF, disconnect solenoid connector and measure coil resistance at the solenoid. Compare to manufacturer specification; replace solenoid if out of range.
  5. Reconnect and backprobe at the harness connector with key ON (engine OFF). Verify reference voltage and ground presence. Do not apply external power unless following manufacturer bench test procedures.
  6. Command the solenoid ON/OFF using a scan tool while monitoring the control signal with an oscilloscope or duty-cycle-capable meter. Verify TCM is outputting the expected PWM or ON signal.
  7. If control signal is present and solenoid is within spec, suspect internal transmission hydraulic issue or intermittent connector contact — consider removing valve body or solenoid assembly per service manual.
  8. If control signal is absent or erratic, trace wiring between TCM and solenoid: check connector pins, continuity, shorts to power/ground, and connector grounds. Repair wiring as needed.
  9. After repairs or component replacement, clear codes and perform a road test and functional tests to confirm the fault does not return.
  10. If all wiring and solenoid tests pass but code persists, consult factory service information for TCM diagnostics, updates, and consider TCM replacement only after exhaustive verification.

Likely causes

  • Corroded/loose solenoid connector
  • Damaged harness (chafing, pinched, rodent damage)
  • Failed solenoid due to electrical or mechanical wear
  • Blown fuse or intermittent power/ground
  • Ground or supply circuit intermittent at TCM

Fault status

⚠️ Status
