P0352, P0351, P1297 Diagnostic Guide for 2001 Chrysler Town & Country 3.3L Engine

Model: 2001 Chrysler Town and Country Fault Code: P0352 Posted: 2016-03-14 18:20

My 2001 Chrysler Town and Country with a 3.3L V6 engine is showing persistent fault codes P0352, P0351, and P1297. The vehicle runs roughly, lacks power, and produces excessive white exhaust smoke. I'm experiencing repeated EGR valve failures—each time the vacuum fittings melt before the aluminum body disintegrates. With only one ignition coil installed, how do I identify which side corresponds to 'Coil A' or 'Coil B'? Additionally, what are the most likely root causes for these codes and symptoms? The MAP sensor was replaced just two weeks ago, and spark plugs and wires were recently serviced—so those aren't the issue. Could a clogged catalytic converter or engine oil burn be contributing to the white smoke and performance loss?

Coil B refers to the primary (control side) circuit of the ignition coil, while the secondary side is the spark-producing portion. A faulty coil could cause P0352 or P0351. However, ensure spark plugs and ignition wires are in good condition—worn components can draw excessive current from the coil, leading to overheating and failure. The presence of other codes suggests a potential MAP sensor issue as well.

I've seen EGR valve failures on this model where the vacuum hose melts first, followed by complete disintegration of the cast aluminum valve body. In some cases, the failure is sudden and violent—like a small explosion inside the exhaust system. This often leads to white smoke and loss of power. Replacing the EGR valve may resolve symptoms, but it's important to address underlying causes like oil consumption or engine wear.

While the MAP sensor was recently replaced, persistent codes suggest other factors. White exhaust smoke could indicate oil burning—common in older 3.3L V6 engines with worn piston rings. A clogged catalytic converter can also cause overheating and power loss, especially if it's restricting exhaust flow. Check engine temperature; if the engine is running hot or producing steam, that’s a serious sign. Ensure the EGR system is fully functional and consider inspecting for oil leaks or internal engine wear.
