P2EC0
Serious Severity (Level 4)Turbocharger Compressor Outlet Temperature Sensor Circuit Low
P2EC0 usually means turbocharger Compressor Outlet Temperature Sensor Circuit Low.
Can you still drive with P2EC0?
⚠️Limited driving — get to a repair shop within 1–2 days. Avoid long trips and highway speeds.
Typical repair cost: $200 – $2500
Severity Level 4 — Serious
This code indicates a serious issue that can cause noticeable driveability problems and potential engine damage if not addressed. The vehicle should be taken to a mechanic as soon as possible. Extended driving is not recommended.
Common Symptoms
- Check Engine Light illuminated
- Turbocharger reading zero or abnormally low
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the turbocharger/boost system
Possible Causes
- Failed turbocharger wastegate — internal resistance has increased, outputting a signal lower than specification
- Damaged wiring or corroded connector in the turbocharger/boost system circuit introducing high resistance
- Short to ground in the turbocharger/boost system signal wire — wire chafed through, signal voltage pulled low
- Loose or oxidized ground connection for the turbocharger wastegate — clean the ground and retest before replacing parts
- Low system voltage (weak battery or failing alternator) causing sensor reference voltage to sag
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($5-127 at shop, free at auto parts store for basic scan)
- Visually inspect the turbocharger/boost system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $124 diagnostic fee at shop)
- Test turbocharger wastegate with a multimeter at the connector — compare readings to factory service manual specs. If out of spec, replace turbocharger wastegate ($200-2500)
- Check the reference voltage supply to turbocharger wastegate — should be steady 5V (or 12V) — if low, trace back to PCM/BCM voltage regulator ($143-398 if module repair needed)
- Perform a voltage drop test on the ground side of the turbocharger/boost system circuit — more than 0.1V drop means a bad ground that must be cleaned/repaired ($81-202 at shop)
