PO441 Diagnostic Code in 2005 Chrysler Town & Country: Causes and Dealer Pricing Concerns

Model: Chrysler T&C Fault Code: P0441 Posted: 2007-12-17 15:19

In November, my check engine light came on and the dealership advised me that the LDP (Lambda Detection Pump) needed replacement along with a detector. Two weeks later, the warning light returned, and I'm now receiving a PO44 or PO441 diagnostic code. I'm seeking clarification—does this code typically point to a specific issue in my 2005 Chrysler Town & Country? I'm planning to return to the dealership but want to understand what might be causing it before agreeing to repairs. I've already been quoted unusually high amounts, and I'm concerned about potential overcharging. Thanks, DC

The LDP is one of the most common failure points in 2005 Chrysler Town & Country vans. Was it actually replaced? And what exactly do you mean by 'weird stuff'?

Yes, the LDP was reportedly replaced—though I’m not entirely sure if it was completed properly. The issue with the dealer is primarily related to pricing: I received a quote of $2,500 for repairs, but I wasn’t actually notified of this upfront. I only saw it on my receipt after the service. This appears to be overpricing and unnecessary add-ons—such as recommending power steering fluid replacement, brake fluid servicing, and rotor replacement. It felt like they were trying to sell me a full vehicle overhaul rather than just fixing the issue. I’m not accusing them of wrongdoing, but past experiences have made me cautious about unexpected charges. Thanks for sharing, DC.

It sounds like the dealer technician is now going to leave this unresolved—no further diagnosis or action taken.

I was genuinely surprised when asked about additional services I hadn’t originally requested, especially after a quote that went from $250 to $2,500. While I don’t have direct evidence of wrongdoing, my experience with dealerships in the past has made me skeptical. I’ve learned to question such changes carefully. However, my issue with the PO441 code continues—after returning to the dealer and having them reset the code, the check engine light came back on after just one week. This suggests either a recurring fault or an incomplete fix.
