Toyota Vitz Error Code P1605 - Help required

[rkbladex]

Error Code P1605 (Knock control error)

The possible reason of appearing this code.
first the behaviours of car to be checked
-the car is idling poor
-the car is giving feel of as if one of the cylinder is not working properly in lower RPMs
-Speed limits to 80-90km.

if these are the symptoms then you must check the VVT sensor or we can also call it OCV(Oil control Sensor).
this error appears because once the oil change is over due. the carbon in oil cause the tiny pours in this sensor blocked the proper oil circulation is not there. Just open the OCV Sensor get it washed by solvent (diesel/petrol) and fix it back clear the DTC and drive your car and i hope the same error will not appear any more.

Must give your feedback if you find this tip useful.

I m experiencing following symptoms engine stall (P1603) on lower RPM with AC ON. I have checked there is no issue in AC as AC cooling is good and this issue appear when i accelerate speed from 0 Km to 20 Km or de-accelerate 20 KM to 0 KM when pressing brakes. It is very hard to troubleshoot and very randomly appearing. I have done all change spark plug, clean throttle body, Clean Sensor beneath throttle body (i think MAF Sensor). P1603 Error code come with P1605. See snapshot. I have freeze frame data of P1603 i will share it shortly.

P1605. Check your knock control sensor's harness open it apply decreaser and wash it, and also check your coils. I experience the same issue and was resolved after changing one of the faulty coil.

Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
