Check engine. scan shows VTC control solenoid valve

well it is misfiring so get the car to a shop and get it serviced
like 99.9999% do today (a real show with real tools) seems not.
you have no tools to fix the car and no scan tool
nobody can fix cars lacking the OBD2 scan tool (real)
there are lots of causes. but in school day 1 they say
:bad engine (say compression is 200,.201,202, and 50.PSI (i can do BAR but so can you google PSI to BAR)or KPa.

or bad spark. (bad cops, ?) bad COP boots.
and last bad fueling, misfire felt here is way too rich burn.
in that order.
guessing will be costly and already has.
what if the scan told told you P03xx errors
and was 301. and spark hole #1 , is 50PSI. oops bad engine
or P03xx code for CMP ,and the cam sensor is bad. or cam belt slipped.
what if the P0301 ( my 1 guess) is bad COP, cylinder 1.
there is P03xx code for bad CKP too and P0300 coded means all 4 plugs show misfire. (cam slip or cmp/ckp fails)

1.5T is DOHC engine.

learn to scan he PCM, or go broke fast
the PCM will always see misfire and have DTC P03xx codes
to tell you what's UP, no looking is HUGE FAIL./
code p03 is spark section failure.

RHD car not USA so is UK or one of their infamous Crown colonies
not told. you.
our 1.5L is 2 cams and chain drive, no stinky belt drive good
and low miles is good.
the engine may be VVT got that? if yes it can fail and cause misfire easy and again the scan tool will show that signs of it to a pro.
vvt is called VTC by honda and is complex (more)
VTC is variable valve timing, and the part on the front of the cam can fail for that.
find a real shop this time that knows honda's and VTC and can hold a scan tool.

There are several possible causes and the one that you should check first is the service bulletin on the issue. There is a software update for that car, the dealer has to perform it though. You can call a dealer and ask how much it costs and give them the VIN to see if it has been done before. If it has been done then you need to check a whole host of things that might be causing that:

• Engine oil level
• Dirty engine oil
• Check VTC Strainer for blockage
• Faulty VTC Oil Control Solenoid or circuit
• Faulty VTC Actuator
• Engine mechanical problems

The last one is the timing chain and tensioner.

Possibly a computer (ECCS control unit) malfunction, but first check the white/black wire going to each injector. All should have power on them with ignition key in on. This white/black wire comes from the computer's pin # 58, then is spliced to all 6 injectors. If no power to injectors, check the wire continuity from the ECCS' #58 pin to the injectors.

The ground wire from each injector also goes into the control unit, but individually, so that the control unit may ground the injector circuit and cause pulse.

If the wiring is good, no breaks or shorts, it may be a computer malfunction, but first find out if the variable valve timing affects injector pulsing. I don't know anything about it, but you have 2 VTC (valve timing control) solenoids, one for each side of the engine. Both are located near or on the firewall behind the engine, near the middle. Looks like 3 solenoids there, the middle one is the EGR solenoid, and the VTC solenoids are on each side of the EGR solenoid. Best I can do from a very poor wiring diagram I was looking at.

You checked for spark, but did you check on all six plugs for spark?

It could be a broken wire possibly.

P1384 VTC solenoid failure,This control variable valve timing,when this fails VTC is disabled and your valve timing is fixed at fully ****** postion. This is located at the right side of the engine below cam timing gears

Diagnostic Trouble Code (DTC) P0341 has a generic description of "VTC phase gap".

"VTC" stands for Variable Timing Control. Basically, what the computer is trying to tell you is that it is having problems controlling the variable cam timing in your engine. There are MANY possible causes for this. The MOST COMMON cause is the engine oil level being low or the incorrect viscosity of engine oil being used. also, failure to change the oil at regular intervals can cause deposits that can cause your cam actuator to stick or bind, or your VTC solenoid to stick. Another possible cause is a worn/loose timing chain.

P1110 Intake Valve Timing Control Solenoid Error

From what I've read, the plunger within this solenoid gets stuck, causing this error. Some have had success with applying lube to this part, while others have had to replace it.


The VTC solenoid valve is part of the Valve Timing Control System. The purpose of the system is to achieve optimum valve timing, thus improving engine performance.

The system will vary the intake valve timing according to engine speed, and other inputs received from the coolant temperature and throttle position sensors. The ECM controls the position of the intake camshaft, by controlling the oil pressure to the intake camshaft pulley hub. When the ECM energizes the solenoid, oil pressure is supplied to the pulley hub, changing the position of the hub, thereby advancing the intake valve timing.

1 Remove the VTC valve from the vehicle.

2 Using a fused jumper wire, apply battery voltage to terminal 1, and ground to terminal 2.

3 If the valve is functioning correctly, the plunger shaft in the valve should be extended.

4 If the plunger is not extended, replace the VTC solenoid.

----

1 Disconnect the wiring harness connector from the VTC valve.

2 Using a suitable wrench, remove the VTC from the cylinder head.

To install:

1 Install the VTC in to the cylinder head, by first hand tightening, then using a wrench.

2 Plug the wire harness connector into the VTC valve.

Check 15A fuses, #58 and #59,
- second possibility is stuck relay, check, swap place with same color relay [E32]
- ctrl solenoid valve resistance 1 and 2: about 7ohms at 20?°C (68?°F)

P0011 (Bank 1); P0021 (Bank 2)
- Intake valve timing control performance, There is a gap between angle of target and
phase-control angle degree.
Causes:
- Harness or connectors (Intake valve timing control solenoid valve circuit is open or shorted.)
- Intake valve timing control solenoid valve
- Crankshaft position sensor (POS)
- Camshaft position sensor (PHASE)
- Accumulation of debris to the signal pick-up portion of the camshaft

I'd add one possibility to the list: worn mech VTC parts if over 150k... possible if history contains lubrication problems. (Mech repair will be costly; i'd try locking the system in place.)
All electronics checkups start from voltage checks, at batt, at ECU. Then clean connectors, next test individual sensor inputs: see link p.14 below. Dig more/all info via 'Favorite Links', see link page below - top left corner:

The error concerns the intake valve timing control solenoid (VTC). If you have the 16v transverse engine the solenoid is located on the left of the engine at the back of the cylinder head: look at the four injectors at the rear of the cylinder head and then imagine a fifth one at the left and this is the position of the VTC. If has a electrical connector to the top of it and an oil pipe connection to its side. This device is used to adjust the valve timing through oil pressure action on the cam assembly. A high reading (error code p0077) indicates that the 'ground' wire is either disconnected or broken to the VTC. Disconnect the electrical connector and ensure the the the plug pins and socket are free of oily grime or corrosion that might interfere with electrical conduction. Disconnect the negative terminal from the battery before doing such work. When everything is clean reconnect everything, clear the code and test.
