My 1996 cav. was taken in to get fixed because my c. eng light came on. mech. read a code reading 1887 from the car. it has something to do with the tranny, but when i look it up on the net im lost..... I'm selling it and i need to know whats wrong.....
The code P1887 is an indication of a malfunction with the TCC release switch. The
Torque Converter Clutch (TCC) release switch is part of the Automatic
Transmission Fluid Pressure Manual Valve Position Switch (TFP Val.
Position Sw.). The TFP Val. Position Sw. is mounted to the transmission
valve body. The switch is normally-closed.
switch signals the Powertrain Control Module (PCM) that the TCC is
released. This is accomplished by Torque Converter release fluid
pressure acting on the switch contact, thus opening the switch. When
the voltage is high on the circuit, the Powertrain Control Module
recognizes that the TCC is no longer engaged.
PCM determines that the TCC release switch is open (indicating that the
TCC is not applied) and the TCC slip speed indicates that the TCC is
applied, then DTC P1887 sets.

The easiest way to reset a check engine light on almost any modern car is to disconnect the battery wait five minutes and connect it back up. This will not tell you why the check engine light came on. For that you need a ODBII scanner, but if the issue was a gas cap left off and you have fixed that, then check engine the light should go off. I have found that many auto parts stores will read your car's ODBII codes for free.
do the computer self read.ignition on off on off on then the check eng. light flashes the codes.if the check eng. light doesnt come on at all then computer is not functioning, so no spark. check power fuse eng.compartment. need a manual for codes.
Before you can reset the light you must find out what problem turned it on, once the fault code is read and the diagnostics done and the problem repaired the light can be reset by disconnecting the negative battery cable for 5 minutes. If the problem isn't fixed the light will come back on right away. You will need a shop to read the codes with a special tool called a scanner.
You can reset the light by disconnecting the battery and reconnecting. If you don't fix the problem, the light will return within a day or two.
You should get the codes read and find out what the problem might be. Places like AutoZone will read the codes for free, and may offer a solution.
I have a chevy cav 03 and my problem is just in the gas guage and temp guage now i cant seem to figure out how to fix it but for a quick fix i have jut been pulling out the instrument panel fuse and putting it back in it seems to fix t
The reason you have that code is because the engine is running rich. I would pull the plugs out and check them also check the plug wires. also when have you changed the fuel filter. check the fuel pressure may have a bad pump.
