Melisssketer,
The P 1810 code is usually the transmission, here are some possible causes;
- Faulty automatic Transmission Fluid Pressure (TFP) Manual Valve Position Switch
- TFP Valve Position Switch harness is open or shorted
- TFP Valve Position Switch circuit poor electrical connection
The automatic Transmission Fluid Pressure (TFP) manual valve position switch consists of five pressure switches (two normally-closed and three normally-open) and a Transmission Fluid Temperature (TFT) sensor combined into one unit. The combined unit mounts on the valve body. You could have a problem with any one of these switches. If this is the problem with your car, parts will not be cheap but it can be done without pulling the transmission. I hope this helps, Ray
Hello
When the service engine
soon light (Also called the check engine light) is turned on this is
to alert you to the fact that Powertrain Control Module (computer)
has detected a failure somewhere in the systems it controls, this can
be the transmission or the engine or emission system, there are fault
codes set in the modules memory for these faults. What needs to
happen now is to have the powertrain control module scanned with a
special tool called an OBD2 electronic engine control scanner or a
OBD2 code reader. Once the code(s) are read then you must perform the
diagnostics for each code and make the appropriate repairs based on
the findings of the diagnosis that was performed, this is called
doing "Pinpoint" testing.
