Corolla 2012 altis engine system check light

[faizan7891]

Dear Pakwheelers,
I have been experiencing issue in starting my car, toyota corolla altis 1.6 2012 model with 112921kms on odometer. I got my battery changed recently about one week ago even after this I had difficulty starting my car. Sometimes it would start immediately sometimes on ignition it just did tick and no ignition voice. It would not start no matter how many times i try rotating the key, it will just give a sound of tick and nothing else. I got it checked from a mechanic and he changed the sulf part of the car saying that it eas faulty and not conducting current properly. Then after that car worked fine for one week now again that problem has recurred and along with this engine check light showed up. This same light showed up initially when the mechanic changed the self part. Please help.

Engine Check light definitely means that there is some fault, and it may also be serious one. Exact error code may help in diagnosing the problem and it's remedy accordingly.
Bro, I would advice you to get your vehicle scanned through Computer.

FIRST THING - change your battery terminals. i had similar issue in my 2 cars and its was just stupid bad terminals. make sure do not apply any grease on them. bad terminals hinder proper current flow and car behaves as if its haunted - sometimes fully ok and sometimes very painful.

for check light, firstly just see your air flow sensor attached at air intake pipe. usually that gets disturbed with some hand movements in that area and check light comes up. otherwise scan it

@abid110 thanks sir, this sounds right as this issue started after battery change and when i Apply force on terminals the car starts and check light goes away after sometime...i will surely get terminals checked and update.
Thanks everyone for the help here.

go for slight high power terminals. and i assume you have atleast 65-rating battery installed.

I wanted to share my experience so far on this issue I faced. I got my terminals checked as advised by a pw member above..acc to 2 different electricians the terminals were fine and didn’t need to be changed. The engine check light disappeared and never appeared again that might be due to the hand movement in that particular sensor area i suppose as advised by a member in thr above post. The issue of start up still remained...the electrician attached a relay. After relay the car is starting up perfectly fine till now for about 20 days and no checklights appeared again.
Can you please guide is this relay solution fine or is it something temporary and may bring some major fault in my engine at a later date? Thanks.

@faizan7891 Have the codes read. The 'tick' you described is a classic symptom of a bad starter module. However, the DTC will be able to uncover the real cause of the issue. It is cheap to read the DTCs at any reputable shop, possibly free as well. There is no need for an additional relay and it is, at best, masking the underlying situation. If the starter relay itself was replaced, check if it is the OEM relay. Failure of the prior relay maybe due to issues on the control side (Load side - Did you have a faulty starter? How did you figure that one out?) of the starter relay all the way from ignition to grounding issues. Have it diagnosed. If the new relay, provided it's of OEM spec, fails again you have a problem.
Get that code before a monkey resets it.

BTW - A relay is just an electromagnetic switching mechanism to activate higher-order equipment. Your car has a number of them for different purposes under the fuse box located in the front passenger side of the engine compartment. I believe your Corolla has a printed diagram for relay desc and locs on the underside of the fuse box.

Check that whether this problem occurs when your car is low on fuel, and disappears when its full, if yes then Check your fuel filter and if not replaced get it replaced according to user manual this fuel filter inside the fuel tank needs to be replaced every 65000 km, but even the dealership after above 100,000 km dont change it,
