VTEC Solenoid Control Circuit Range/Performance Problem
There’s a problem with the VTEC solenoid control system's performance.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The VTEC solenoid controls when the engine switches between efficiency and performance modes; if it’s not working right, the engine can’t switch properly.
What the computer is actually seeing
The engine control module (ECM) monitors the voltage and resistance from the VTEC solenoid. It expects the voltage to be in a specific range (around 5-12 volts) and resistance to be within 5-15 ohms. If the readings are outside these expected values, it triggers the P1367 code.
What a healthy reading looks like
Voltage: 5-12 volts; Resistance: 5-15 ohms.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check engine oil level; should be within the safe range. If low, top off and recheck. Decision: Is oil level okay? -> Yes: go to step 2; No: top off oil and monitor.
- 2Inspect the wiring and connectors to the VTEC solenoid for damage or corrosion. Decision: Are they intact? -> Yes: go to step 3; No: repair or replace connectors as needed.
- 3Measure the voltage at the VTEC solenoid connector with the key on, engine off. Expect 5-12 volts. Decision: Is voltage present? -> Yes: go to step 4; No: repair wiring or check the ECM.
- 4Measure the resistance of the VTEC solenoid. Expect 5-15 ohms. Decision: Is resistance within range? -> Yes: further diagnose ECM; No: replace the solenoid.
Common causes
- Faulty VTEC solenoid
- Damaged wiring or connectors
- Low engine oil level
- Faulty oil pressure switch

Frequently asked questions
Is it safe to drive with this code?
It's drivable but expect reduced performance; fix soon.
Will this code come back after clearing it?
If the underlying issue isn't fixed, it likely will return.
Why does this code appear with a misfire code?
A misfire can happen if the VTEC solenoid fails, affecting engine timing.
