Check for a possible short to ground by moving the negative lead on the DVOM to a known good ground, resistance should be very high or over limit (OL). you take on any vehicle. Resistance should be very high or over limit (OL), if it is low, suspect a short to ground. One of the most common problems with the Chevy Colorado is when it throws the P0700 trouble code. Then a few days later I was just driving through town and the CEL came back on. The cause of the problem is debris plugging the converter clutch signal orifice cup plug 238 in the transmission pump cover. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

If no voltage is present, determine the loss of power back through the circuit using the manufacturers wiring diagrams for reference.

start stalling a lot. If one of these reasons for P0741 code is occuring now you should check P0741 repair processes. Take the AutoCodes.com automotive tests and turbo-charge your car repair knowledge. If the cycle stays at 0% or 100% or is intermittent, re-check connections and if all wiring / solenoid is OK, the TCM may be at fault.

When you check Chevrolet Colorado car engine light came on code P0741 the reason should be Engine Light ON (or Service Engine Soon Warning Light). There may be other diagnostic trouble codes associated with the transmission control module that can only be accessed by using an advanced scan tool. Check for voltage on the power side circuit of the TCC solenoid or at the wire harness connector at the TCM with the DVOM set to volts scale, positive lead at the wire being tested and the negative to a known good ground with the vehicles key on/engine off, battery voltage should be present.

Note: This code is similar to codes P0740, P0742, P0743, P0744, P2769, and P2770. Chevrolet Colorado P0741 Code Meaning : When you check Chevrolet Colorado car engine light came on code P0741 the reason should be Engine Light ON (or Service Engine Soon Warning Light). (adsbygoogle = window.adsbygoogle || []).push({}); The engine and transmission are actually connected by a fluid coupling mechanism inside of the torque converter which is what multiplies the torque until the speeds equalize and create a "stall" speed where the difference in actual engine RPM and transmission input RPM is around 90% efficient. P0741 Avalanche Colorado Express Silverado Suburban Tahoe Trailblazer Fix code P0741 TCC Stuck Off GM has issued a technical service bulletin PIP4329 to address trouble code P0741 and a check engine light.
