P0440 OLDSMOBILE code

When code P0440 is set, a leak has been detected by the Engine Control Module (ECM), or a vapor pressure sensor has malfunctioned. The ECM determines this when the vehicle is turned off, and the vent control valve is commanded closed. How do I fix error P0440? What repairs can fix the P0440 code? Tightening […]

P0842 OLDSMOBILE code

The P0842 code indicates that there has been an abnormally high voltage reading from the transmission fluid pressure sensor circuit. Other shift solenoid, transmission slippage, lock up, gear ratio, or torque converter clutch codes are often stored in the PCM with the P0842 code. Where is the transmission fluid pressure sensor switch? The pump pressure […]

P0307 OLDSMOBILE code

What the P0307 code means. When the P0307 diagnostic trouble code is stored by the Powertrain Control Module (PCM), it is an indication that a misfire has been detected in cylinder 7. More specifically, the PCM detects an increase or decrease in crankshaft revolutions per minute (RPM) that exceeds 2%. What could cause a P0307 […]

P0717 OLDSMOBILE code

Code P0717 is triggered when the transmission’s Input Speed Sensor isn’t providing a signal. This is a critical problem because with out this signal, the Transmission Contorl Module or TCM can’t properly shift the vehicle from gear to gear as the vehicle needs to change speed and rates of acceleration. How do I fix code […]

P0060 OLDSMOBILE code

P0060 indicates that there is a malfunction in the oxygen sensor located after the catalytic convertor. The oxygen sensor is used to regulate the performance of the engine, such as fuel consumption. However the O2 sensor can only accurately regulate the engine performance after the sensor has reached a hot temperature. What is HO2S heater […]

P0463 OLDSMOBILE code

Diagnostic trouble code (dtc) p0463 stands for “fuel level sensor “a” circuit high.” it means that there is an unusually high voltage signal coming from your vehicle’s fuel sensor. How do I fix error P0463? Some of the most common fixes for a P0463 code include: Repairing or replacing the fuel tank. Repairing or replacing […]

P1174 OLDSMOBILE code

How do I fix error code P1174? In this case, the fix is as simple as replacing your O2 sensor, which costs about $50 and can be DIY’d easily. After replacing your O2 sensor, if you continue to receive P1174 or P1175 engine codes, you should check your MAF and try cleaning or replacing that. […]

P0452 OLDSMOBILE code

A P0452 trouble code is related to the part of a vehicle’s emissions control system, or EVAP, that controls fuel tank pressure. This is usually called the fuel tank pressure sensor or the evaporative pressure sensor. Where is the EVAP pressure sensor located? The fuel tank pressure sensor is part of the fuel pump assembly […]

P0172 OLDSMOBILE code

What the P0172 code means. P0172 indicates that there is too much gasoline being detected in the exhaust gases exiting the combustion chamber. The ECU uses a number of instruments, such as the mass air flow sensor (MAF), oxygen sensors, and manifold absolute pressure (MAP) to monitor the air-fuel ratio of the engine. What would […]

P0230 OLDSMOBILE code

P0230 is a diagnostic trouble code (DTC) for “Fuel Pump Primary Circuit Malfunction“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. What is a P0230 code? Diagnostic trouble code (DTC) P0230 stands for “Fuel Pump Primary Circuit.” This code […]
