P0154 is a relatively common trouble code. It’s generic, which means that it has the same meaning for any vehicle with OBDII (Fiat Punto or not). It means that the PCM/ECM is not detecting any activity from the sensor. There can be many reasons for this code to throw. These include a bad o2 … Read more
P0134 is a relatively common OBDII trouble code. It’s generic, which means that it has the same meaning for any vehicle with OBDII. It means that the PCM/ECM is not detecting any activity from the sensor. P0134 Definition P0134: O2 Sensor → No Activity Detected →Bank 1 Sensor 1 The Punto’s computer uses the … Read more
P0403 is a very common trouble code. It is a generic code, which means that it has the same meaning for the Fiat Punto as it would any other vehicle. It affects the EGR (Exhaust Gas Recirculation System and technically means: P0403: EGR→ Circuit Malfunction A circuit malfunction implies that there is a wiring problem … Read more
With the Fiat Punto, P0404 is going to have the same meaning as it would in any other vehicle. It’s a generic powertrain code that stands for: P0404: EGR Circuit → Range/Performance While there are several issues that can throw the P0404 code in the Punto, the most common issue is either going to be … Read more
The Fiat Punto utilizes a crankshaft position sensor in order to regulate the engine timing. This sensor uses a reluctor to gauge the position of the crank. When the Punto’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code. P0335 Symptoms: Fiat Punto … Read more
P0138 is a common OBDII code that occurs in many vehicles, including theFiat Punto. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more Voltage to the sensor is to high (wiring problem, think short) Bad O2 sensor itself There are also some less likely problems … Read more
P0133 is a common OBDII code that occurs in many vehicles, including theFiat Punto. The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels. The O2 sensor is responsible for helping the ECM meter oxygen levels in the exhaust in order to … Read more
P0132 is a common OBDII code that occurs in many vehicles, including the Fiat Punto. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more. The air fuel sensor stays in rich biased mode for too long. There are also some less likely problems that can … Read more
The P0131 code is an OBD-II diagnostic trouble code that indicates low voltage in the Fiat Punto’s Oxygen (O2) sensor circuit for Bank 1, Sensor 1 (B1S1). This sensor plays a crucial role in maintaining optimal engine performance by detecting the air-fuel ratio in the exhaust, then sending this data to the Punto’s engine control … Read more
P0330 is a powertrain OBDII trouble code that has the same meaning for the Fiat Punto as it would any other vehicle. By definition, it means that the vehicles ECM/PCM isn’t getting the proper signal from the knock sensor. Clearing this code typically requires a new knock sensor. The second most common cause is … Read more
