SOURCE: GM service engine code P1870/2000 GMC Sonoma 2.2 cylinder

you jave a biggie here.
here is some info
CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) monitors the difference between engine speed and transmission output speed. In D3 drive range with the TCC engaged, the engine speed should closely match the transmission output speed. In D4 drive range, with the TCC engaged, the TCC slip speed should be -20 to +60 RPM .

When the PCM detects excessive TCC slip when the TCC should be engaged, then DTC P1870 sets. DTC P1870 is a type B DTC.

CONDITIONS FOR RUNNING THE DTC

  • No TP sensor DTCs P0122 or P0123.
  • No VSS assembly DTCs P0502 or P0503.
  • No TCC solenoid valve DTC P0740.

  • The TP angle is 12-50% .
  • The vehicle speed is 56-112 km/h (35-70 mph ).
  • The speed ratio is 0.64-0.95 (the speed ratio is the engine speed divided by the transmission output speed).

SOURCE: Truck losing power and service engine soon light on

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

SOURCE: 1998 GMC Sonoma threw code P1133 02S 1/1

P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1
I would have the repair shop see if they either damaged or left disconnected the oxygen sensor for engine cylinder bank one upstream sensor, this sensor would have been disconnected if the oil pan was removed.

SOURCE: GMC envoy after I filled gas tank the low fuel

You will need to replace the fuel level sensor which is in the fuel tank.They have a lot of problems because the metal fingers on the sensor wear off and gives you the incorrect readings.This will also cause the check engine light to come on.You will probably have a level sensor code.This will be a lot easier if the fuel level is down to about a quarter tank or less.Also you should be able to get just the level sensor and not have to get the complete fuel pump module.Good luck.

Factory alarm problem o 1999 gmc sonoma


Do a reset. Turn it on for ten minutes, off for thirty seconds. Try to start. There is also a relearn procedure. Do this three times, try to start after the third time. Have it on a battery charger. After that you need to have t scanned for codes. Code readers don't read security.

Are you trying to reset the "Check Engine Light"? If so, go to your local Autozone/ O'Reilley's/ Advanced Auto and borrow one of their engine code readers. You can reset the CPU using the code reader.

sounds like a bad ignition module check for spark when it dies if you do not have spark at plugs check between coil and coil wire if still no spark most likely module it is under rear of distributer cap resembles a black wafer board with two electrical plugs

First, you need to have it scanned for codes, then you will know what to look for. Dont replace anymore unneeded parts until you get a trouble code. you will need a OBD1 scanner. You will only know the cost and cause when you find the problem.

These old style check engine lights are pretty much just service reminders, and as such can be reset generally just by taking off the negative battery cable for about 1 hr. Still need to read codes, though. Check all your vacuum lines.
