the fault codes are for a misfire problems check the ignition system like spark plugs/on plug coils you dont say the what engine in your vehicle so not easy to answer your question in more detail

This points towards the number 2 cylinder ignition coil or ignitor circuit malfunctioning. If it is intermittent, your car will have and lose power, making the engine run like a bucking bronco. A diagnosis is in order, it could be a wiring issue or a bad spark plug causing the symptom. Could also be ignition coil or ignition module. Should be a quick repair.

DTC P1315 is Igniter Circuit Malfunction (No.2).
Check No. 2 ignition coil.
See the link below for more information from a 2000 to 2002
Toyota Echo Service Manual.
Diagnostics: Engine: P1300, P1305, P1310, P1315 Igniter Circuit Malfunction (Echo)

Hope that helps.

you have a misfire on cylinder # 2, check your plugs, if ok swap coils clear eng lite, run vehicle until check eng. lite comes back if code changes to a dirferent cylinder then you have a bad coil, if same code repeats then you need an injector, good luck.

P1305 Igniter Circuit Malfunction No. 2 (1998-2000 Land Cruiser, 2000 Celica & Tundra)
this code is a toyota code so i would say it means the coil but the generic code says its cylinder no 5

P0305....Cylinder 5 Misfire Detected

so somewhere their is a faulty coil

What is P1300,1305 1310 on a Toyota

They are MFG Specific

Get them and I will try and offer some suggestions

302 is #2 but Iam thinking if you find that
those other codes are Cam Sensors, then
we will discuss that

P1300 = ignition system malfunction (#1 coil/igniter circuit fault)
P1305 = same as above but #2 coil
P1310 = #3 coil
P1315 = #4 coil

Try a new plug . Switch wires just to rule them out. Do a compression test on that cyld.

P1305 Igniter Circuit Malfunction - No. 2

Call or visit your local toyota dealer. Purchase an ignition coil. $85 The #2 cyclinder is the passanger side front.

Take that plastic V8 siver cover off and throw it away. Unplug the wire connection that looks like the piece you purchased. Remove the 12mm bolt that is holding the old one in place. It is pushed onto the sparkplug below. Pull out the old one. Push in the new one. reinstall the 12mm bolt. plug in wire connection. I believe the #2 can be reached without removing the plastic air intake.

Hope helps (remember to rate and comment this).
