2003 Chevrolet Venture with P0131, P0171, P0300, and P0453 Codes - Sputtering, Loss of Power, Fuel Issues

Model: 2003 chevrolet venture Fault Code: P0131 Posted: 2017-09-24 22:51

My 2003 Chevrolet Venture has been experiencing intermittent performance issues, including severe sputtering, loss of power, and a sensation that the engine is not receiving fuel properly. The onboard diagnostic system has logged multiple trouble codes: P0131, P0171, P0300, and P0453. I'm concerned whether these codes are all related to the catalytic converter or if they point to a broader issue such as fuel delivery, air intake, or sensor malfunction. Any insights into diagnosing or resolving this would be greatly appreciated.

P0131, P0171, and P0300 codes suggest issues with the oxygen sensor, fuel mixture, and potential misfires. Start by checking fuel pressure using a gauge to ensure proper fuel delivery. Additionally, address DTC P0453 — this indicates a high voltage issue in the fuel tank pressure sensor circuit, which may affect fuel system performance.

I recently unhooked the mass air flow (MAF) sensor and noticed immediate improvement in engine performance. While this is not a permanent fix, it raises the question: can the MAF sensor be cleaned instead of replaced? Cleaning may restore functionality without the cost of a new part.
