P1603 Engine stall history (you have had this code since you bought the car) seems cleaning the throttle body did not solve the issue.
After starting the engine, this Diagnostic Trouble Code (DTC) is stored when the engine stops without the ignition switch being operated. With the engine running, the engine stops (the engine speed drops to 200 RPM or less) without the ignition switch being operated for 0.5 seconds or more. It is necessary to check if the vehicle has run out of fuel before performing troubleshooting, as this DTC is also stored when the engine stalls due to running out of fuel.

P1604 Related to P1603 P1604 TOYOTA - Startability Malfunction, The P1604 code is stored if the engine does not start or continues to crank without starting for a certain period of time. The P1604 code is also stored if the vehicle has run out of fuel. It is necessary to check whether there was enough fuel in the fuel tank before performing this inspection.

P1605 - Engine Stall History - After starting the engine, this Diagnostic Trouble Code (DTC) is stored if the engine speed drops below the set speed. With the engine running, the engine stops (the engine speed drops to 200 RPM or less) without the ignition switch being operated for 0.5 seconds or more. It is necessary to check if the vehicle has run out of fuel before performing troubleshooting, as this DTC is also stored when the engine stalls due to running out of fuel.

Good afternoon Chief Gazzuz, i currently have a persisting problem in my toyota rav4 2007 with 2gr-fe Engine. I only wished i am based in Lagos, I would have visited your workshop.

The car lags. When i try raise fire by pressing the gas pedal, the response from the engine is not instant. Most times when i get to a junction and want to join the traffic, it lags before moving like a bullet.

We have changed spark plugs, checked the coils, serviced the injectors and replaced the fuel pumps twice, yet the problem persists.
we currently have:
DTC codes: 1 p2402 Evaporative Emission System Leak Detection pump control circuit high.
2 p2419 Evaporative Emission System switching Valve Control Circuit Low.
3 p 2401 Evaporative Emission System Leak Detection pump control circuit low
4 p043E Evaporative Emission System Leak Detection Reference orifice Low Flow
5 p043F Evaporative Emission System Leak Detection Reference orifice High Flow

Pls could this be the problem with the car?

Thank you Baba Gazzuz

GAZZUZZ:


2GR is notorious for sensitivity to sparkplug gaps . Check sparkplugs .

mrsdaniel:


Ok we just removed one of the three front facing plugs for inspection. Kindly assist if this is a good plug

GAZZUZZ:


You would need a sparkplug gaps tool, to check. 1.1mm

mrsdaniel:


Okay i really appreciate. I'll simply create time & change the iridium plugs.

GAZZUZZ:


clean out the injectors while at it .

akara:
Good morning house, can someone help with the shown warning light. What it means. Thanks in advance.

Low tyre pressure.

You should read your vehicle manual, it's in the glove box compartment on the front passenger side

Gazzuzz is a genius

He's a nice person. It's not easy to find someone in Nigeria giving out his wealth of knowledge and experience for free. They'd rather prefer to die with it.

Boss, is it this one

GAZZUZZ:


there's a lot of games out there, buy original

Good morning oga GAZZUZZ

I bought a Toyota Corolla 2010 and I am intending on changing the four tyrres but there has been some confusion on what guideline to follow.

The vehicle manual specifies tyre size to be P205/55/R16 89H
While the label on the driver's door is specifies P199/65/R15

I now decided to check the tyres that came with the car and found 195/65/R15 * 91H

The first picture is the vehicle manual while the second picture is the one I snapped on the driver's door


Which tyre specification would you advice I buy for the car
