P08DAShift Solenoid K Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Points to a control circuit of shift solenoid K that is neither open nor shorted, yet whose measured values, usually coil current, do not fit the commanded state. No manufacturer documents this code publicly, and the analogue for solenoid A, P0972, is not used in the GM or Ford sources either. Ford covers the same failure with an electrical current check that trips when the feedback current stays out of range for 0.5 seconds. Causes are typically a coil with changed resistance, a high-resistance contact or a weak TCM driver. CARB requires output circuits to be checked beyond plain opens and shorts. P08DB, P08DC and P08DD cover low, high and open. The valve may switch late or incompletely.
- What you may notice
- Check engine or transmission warning light on
- Delayed or soft shifts
- Possible limp mode
- Likely causes
- LikelySolenoid coil resistance out of specification
- PossibleCorroded or loose pins adding resistance
- RareTCM output stage no longer delivers correct current
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €100 – €1,500
