Dodge ram 1500 2000 took it to auto zone and they stated change pressure sensor switch which i did and two days later it was doing the same thing and code p1756 came up
Contrary to popular belief (and sometimes the salesperson's claims), AutoZone is not a repair shop. They can read the codes and tell you what the code means, but buying parts doesn't always fix the problem. You can check the link provided, or you can take your Ram to a professional shop, where they (normally) warrant their work.
have code p1756 on my dodge ram 1500 44 What could be the problem how much...
SOURCE: OBD II Code P1756.
Could be a bad sensor, but it's transmission related. Anything affecting internal trans pressures should be taken care of by a reputable trans shop.
SOURCE: how do i change the power steering pressure switch
From the Factory Service Manual, you can get one relatively cheap from www.promanuals.net. Here is a link to your 2004 Dodge Ram Service Manual.
The power steering pressure switch is installed in
the power steering high-pressure hose (Fig. 9).
(1) Disconnect electrical connector from power
steering pressure switch.
(2) Place a small container or shop towel beneath
switch to collect any excess fluid.
(3) Remove switch. Use back-up wrench on power
steering line to prevent line bending.

You can get this code if you don't tighten the gas cap all the way, or the gas cap is bad. I will put all the detail for the code below and what I would do to fix the problem...
NOTE: Do not top off your tank either. This could cause the 'overfill check valve' to fail, and could cause this code.
Definition of P0441: Evaporative Emission Control System Incorrect
Purge Flow
Detection logic:
DTCs P0441 and P0446 are recorded by the ECM when evaporative emissions leak from the emissions components
or when there is a malfunction in either the VSV for EVAP, the VSV for
pressure switching valve, or in the vapor pressure sensor itself.
detection cause: Pressure in charcoal canister and fuel tank does not drop or
drop in pressure increased beyond the specified limit during
purge control (2 trip detection logic)
What I would do:
1. Replace fuel cap and reset computer. If code returns, then proceed to next
The next steps require a diagram, so the purchase of service manual to locate the components is very helpful
2. Check for vacuum leaks in ALL emission hoses
3. Check VSV valve operation (there are three; they are ~$75 new from dealer, and sometimes fail)
4. Check for cracks or leaks around or in the charcoal canister (usually requires a smoke machine)
5. check for voltage to VSV's
6. Last resort: take it to the dealer and have them run a diagnosis. This should run between $50-$100.
Good luck!
