Are there any problems with the Honda VTEC system?
Honda Vtec System Testing Diagram. There is an additional problem that Civic SI, CRV and Honda Accord owners probably wouldn’t expect to find on their reliable Honda. Another common symptom of Honda VTEC system problems becomes an oil leak that develops slowly, but consistently worsens over time.

What causes an oil leak in a Honda VTEC?
Another common symptom of Honda VTEC system problems becomes an oil leak that develops slowly, but consistently worsens over time. The VTEC solenoid actually allows oil to flow to the internal galleries of the overhead camshaft. This means that the housing of the solenoid is holding back full engine oil pressure.
What causes a VTEC control solenoid to go bad?
If your fault is NOT due to a faulty pressure switch, or an electrical circuit fault to or within the PCM, then it is either a bad VTEC control solenoid, sludge clogging the oil circuit OR low oil pressure / oil starvation. Good luck! IT IS ALREADY BROKEN DOWN AGAIN!!! The dealer where you bought it? A non -Honda dealer, right? Click to expand…

Why does my Honda engine not start up?
A very common reason for this symptom is a problem with the main relay—an electronic device that opens and closes the fuel supply to the engine. To determine if you indeed have this problem, try the following test: Use a piece of stiff wire to hold the throttle linkage at a set position and set the engine speed at about 2,500 rpm.
How does the VTEC work on a Honda Accord?
It accomplishes this by turning a control solenoid ‘ON’ to allow oil pressure into the VTEC control passages to apply pins that will lock the intake rockers. When the oil pressure is present, the pressure switch signal will go high. When the control solenoid is turned ‘OFF’, the oil pressure is dumped and the oil pressure switch signal will go low.
Why does my Honda VTEC go into fuel cut mode?
If the pressure switch signal is not logical for the commanded state of the control solenoid, a DTC will set and the PCM will go into a ‘fuel-cut’ mode limiting engine rpm and performance. The PCM simply doesn’t ‘know’ what the state of the intake valves are, so you end up with the symptoms you describe.
What does the VTEC solenoid on a Honda do?
The VTEC solenoid is that switch; it diverts oil from the low-lift cam lobe to the high-lift cam lobe. If the VTEC doesn’t get the signal, is clogged, or leaks then problems occur.
What to do if your VTEC is not working?
Clearing the DTC, disconnecting the VTEC oil pressure switch and using a jumper wire to short the signal wire to ground and keeping your RPM below 2700 when driving would prevent VTEC from engaging and you could operate your vehicle. This ASSUMES that you actually do have engine oil pressure to keep from grenading your engine.
