Suzuki Ignis Oil Warning Needs Urgent Sensor Fix

I had a similar issue with my 2005 Suzuki Swift diesel last year. As someone with moderate experience working on cars, I initially thought the oil sensor readings were incorrect when the warning lights appeared. After running car diagnostics, the mechanic found that the oil gauge was actually working fine, but there was a damaged wire connection to the temp sensor. The warning lights were triggering because the ECU wasnt receiving proper signals from the engine sensors. The repair involved fixing the wiring connection to the temperature sensor and cleaning the connector pins. Total cost was 95€ for parts and labor, which solved both warning lights issues. Before suggesting specific fixes for your Ignis, could you share: Current mileage, When the warning lights first appeared, Whether oil pressure and temperature readings fluctuate while driving, Any unusual engine noises or performance changes This information would help determine if youre dealing with the same car sensor issue I experienced or something different. Its important to address oil pressure warnings promptly to prevent engine damage.

Thanks for the detailed explanation about the wiring issue. My Ignis has 75948 KM and had its last service 3 months ago. The warning lights started appearing intermittently about 2 weeks ago. The oil pressure gauge does fluctuate slightly when idling, but stabilizes at higher RPMs. No unusual engine noises so far. The automotive sensor diagnostics from my basic OBD reader showed codes related to oil pressure, but I wanted to confirm if cleaning the sensor connections might work before spending money on new parts. Based on your experience with the wiring fix, I will have the connections checked first. Could the engine temperature sensor also be affecting these readings? The timing of these issues right after a regular service makes me wonder if something was disturbed during maintenance.

Thanks for providing those details about your Ignis. The symptoms you describe definitely mirror what I experienced with my Swift, especially the gauge fluctuation at idle and stable readings at higher RPMs. The timing after your service is interesting. On my Swift, the oil temperature sensor connections had been disturbed during routine maintenance, which caused intermittent false readings. The engine temperature sensor and oil pressure readings are indeed interconnected in these models, as they share some wiring pathways in the sensor network. After my experience, I learned that the engine temperature sensor can trigger oil pressure warnings if its sending incorrect signals to the ECU. The temperature readings affect how the system interprets oil pressure data. First steps I would recommend: Have the wiring connections inspected, particularly around the oil temperature sensor, Clean all sensor connection points, Check for any loose ground wires near the engine temperature sensor, Verify the oil pressure sensor connector is properly seated These checks should cost significantly less than replacing parts. My repair started with a 45€ diagnostic fee, which was applied to the final repair cost. If cleaning and reconnecting dont resolve the issue, then consider sensor replacement. The stable readings at higher RPMs suggest this is likely an electrical rather than mechanical issue, just as it was in my case.

Thanks for the advice, you've convinced me to start with checking the wiring and connections first. The similarity between your Swift's symptoms and my Ignis issues is reassuring, especially the part about how the oil temperature sensor affects pressure readings. I've booked the car in for next week to have all the automotive sensor connections checked and cleaned. The mechanic quoted 40€ for initial diagnostics, which seems fair based on your experience. They'll focus on inspecting the wiring around both the oil gauge and engine temperature sensor areas. I feel better knowing this might be fixed without replacing expensive parts. Will update once I know if cleaning the connections solved the oil pressure warnings. Really appreciate you sharing your repair experience, it helped narrow down the likely causes and saved me from jumping straight to sensor replacement. Just one more question, should I limit driving until the inspection, or is it safe to continue normal use since the readings stabilize at higher RPMs?
