I did a manual scan in my car and threw me the following flashes:
I found the Check Engine
** 1: Primary O2 Sensor Open or Short circuit in O2 sensor, bad O2 sensor Primary
** 7: Throttle Position Circuit Reading too high, low, short or open, bad TPS
* 22: VTEC System Malfunction Short or open circuit in VTEC, bad VTEC solenoid valve, pressure switch VTEC Bad

But also the light of the D4 Transmission
25:

-ABS
* 13:
* 14:
* 81:

Could someone help me for complete the info?

Before you start throwing parts at the car, check your electical harness. Unlikely all these components to go bad at once. More likely a faulty connection, bad ground, or damage to the harness somewhere.

25- 2nd Clutch Pressure Switch, this is located at the top of the bell housing, under the radiator hose/intake manifold, it screws in from the engine side. Check the wire harness.

13- Left front wheel sensor (open/short to ground/power)
14- Left front wheel sensor (signal degradation/noise, intermittent)
81- CPU diagnosis, ROM/RAM diagnosis.


I have a sneaky suspicion the car was in an accident and needs the wire harness given a once over. Recheck grounds and power connections first before going full on diagnostics.

Thank you MAD MIKE. I'll check the harness like you said.
The symptom that presents my car is that when wanting to gain 3,250 rpm needle starts to bounce and tug engine. What both have to do with the TPS?

If the TPS, O2, and VTEC are not properly functioning the car will probably stumble a bit. If the ECU is in limp mode the engine rpms will be limited.
