P08E5Shift Solenoid L Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- High-voltage fault in the control circuit of shift solenoid L, set when the line shows battery voltage or a floating high level while the TCM expects otherwise. No manufacturer documents this code publicly. The analogue for solenoid A illustrates the two possible readings: in GM's 6-speed tables P0974 covers an open circuit as well as a short to power, fails after 1.2 of 1.5 seconds and needs two trips for the MIL, whereas Ford's P0974 only means a short to power. A wire chafed against a powered conductor inside the transmission harness is a typical cause. CARB requires the check. P08E4 is the low counterpart, P08E6 the open circuit. The valve may stay on, giving wrong gears.
- What you may notice
- Check engine or transmission warning light on
- Wrong gear selected
- Harsh engagement or limp mode
- Likely causes
- LikelyControl wire chafed against a powered conductor
- PossibleOpen coil on systems that read opens as high
- RareTCM output stage fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
