P0336 & P1750 error code, VITZ starting issue

[engr.burhan]

Hi Pakwheels Community,
From last 2 days my VITZ was showing unusual behavior while starting the car, it was not starting in first attempt, when i turn off the lights / AC then it started, i was assuming that there is a battery problem, but few hours ago car was not starting at all, after 2 hours of rest when i again tried car started but there was check engine light, when i check the error code with OBDII it was showing P0336 & P1750, i have checked little detail at google, can you please suggest me which mechanic is best in Lahore for this issue, preferably near emporium Johar town

@Xulfiqar can you please share the reason of these codes

Is the battery old, new, or in warranty? What is the condition of terminals?
Try changing the battery and clear the codes. Update us then.

This is not a battery problem but a problem in the crankshaft position sensor circuit wiring or sensor itself

However another anomaly can set this 0336 code, that anomaly is running the engine out of fuel.

The 1750 code is transmission pressure control solenoid circuit,

Do you have a regular mechanic to fix your car? Or you shop around each time it needs repair?

Thanks brother for your response,

Today i have replace the crankshaft sensor, since i have mistakenly clear the alarms through OBDII before replacing the sensor so it's unknown whether issue has resolved or not, it will confirm in a day or two when i will drive the car, furthermore i have checked old crankshaft sensor reading with multimeter (in ohms & at diode continuity) it is showing values & that values are also changing while rotating some metal infront of the sensor, which means sensor may was okay

I always keep the fuel up
I only visit when it needs repair,

can you plz confirm the solution of 1750 ? the electrician who changed the crank sensor asked me to change the car gear oil for P1750, i don't think so it will work, as per my knowledge P in the code is indicating power issue

Fujika battery was installed around 15 months ago, physically battery is in okay condition, also showing green indicator

[Xulfiqar]

The P1750 code is a faulty pressure regulator inside the transmission. It can be a lot of issues, like wiring, internal wiring, stuck solenoid due to excess metal shavings (very common), hydraulic leak in the valvebody of the transmission etc.

And yes P stands for powertrain

Have you any idea who is the best electrician for this purpose in Lahore ?
