SOURCE: p1810 transmission pressure manifold switch fault

P1810....ATF pressure manual valve position switch malfunction. I think it is external. but i could find little information on this particular code. it is probably attached on the transmission itself. it should have a vacuum plug attached.

I have a 2001 Chevrolet Impala with about 94,000 miles on it. I took it to a parts store to run a diagnostic after noticing the "Check Engine" light on. The code it threw was a p1810 - TFP VALVE POSITION...


with a scan tools look for data of transmission.
then look for A,B,C,D switch data and compare with chart
these valve are there to confirm oil pressure has been going to the right component.
see witch one of a b c d switch malfunction and have a test to wire from transmission to pcm
signal to pcm it's only a logic pattern on and off state
on is grounded
off is not grounded then if wire is ground then it send a message of malfunctionning switch or oil pressure inside transmission but do the outside diagnosis before
hope it helps

Codes p0014, p0016 and p1810


Code 14 is for a problem with the exhaust cam sensor, code 16 is for a problem with the crank and cam sensor correlation.
Code 1810 is for a problem with a pressure switch, but it is usually inside the transmission and involves the torque converter.

Transmission pressure switch manifold fault explanation p1810


Hi there:
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.
The Powertrain Control Module (PCM) supplies ignition voltage for each range signal. By grounding one or more of these circuits through various combinations of the pressure switches, the PCM detects which manual valve position you select. The PCM compares the actual voltage combination of the switches to a TFP manual valve position switch combination chart stored in memory.

The TFP manual valve position switch cannot distinguish between PARK and NEUTRAL because the monitored valve body pressures are identical. With the engine OFF and the ignition switch in the ON position, the TFP manual valve position switch indicates PARK/NEUTRAL. Disconnecting the AT inline 20-way connector removes the ground potential for the three range signals to the PCM. In this case, with the engine OFF, and the ignition switch in the ON position, D2 will be indicated.

When the PCM detects an invalid state of the TFP manual valve position switch circuit by deciphering the TFP manual valve position switch inputs, then DTC P1810 sets.Action Taken When the DTC SetsThe PCM illuminates the Malfunction Indicator Lamp (MIL) during the second consecutive trip in, which the Conditions for Setting the DTC are met.The PCM commands D2 line pressure.The PCM commands a D4 shift pattern.The PCM freezes transmission adapt functions.The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.The PCM stores DTC P1810 in PCM history during the second consecutive trip in, which the Conditions for Setting the DTC are met.Since the computer does not know what gear range the transmission is shifted into, it defaults to a higher line pressure to protect the transmission. It also commands the transmission as if it were in the D4 position. The transmission will still shift normally through all the gears, shifts may be more firm than normal. No damage will occur to the transmission if driven even for prolonged periods with this dtc set. It is far more likely that the loss of transmission fluid damaged the transmission.

Hope helps.

A trans shop will need to check it for you. Its not ON the trans its IN the trans. Have your local repair shop recommned a trans shop (theres a lot of crooks out there, stay away from any chain store)
