DTC P1093
Fuel Rail Pressure Low During Power Enrichment



The engine control module (ECM) uses the fuel rail pressure (FRP) sensor to determine fuel pressure to the fuel injectors. This is then compared to the calculated target fuel pressure as determined by the ECM. The ECM adjusts the FRP by modulating the duty cycle of the control driver of the fuel pressure regulator. Injector pulse duration is determined by the measured rail pressure and the target injection fuel into each cylinder. If a sensor circuit malfunction is detected, or the commanded fuel injection pump flow is not within the proper range for a given engine load and speed, DTCs will be set.

DTC U1000 and U1255 Circuit Description Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the identification number of the module which sent the message for State of Health monitoring. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. When a module does not associate an identification number with at least one critical parameter within about five seconds of beginning serial data communication, DTC U1000 or U1255 is set. When more than one critical parameter does not have an identification number associated with it, the DTC will only be reported once. The class 2 serial data line on this vehicle is a ring/star configuration. The following modules communicate on the class 2 serial data line:
• The body control module (BCM) • The digital radio reciever • The driver door module (DDM) • The electronic brake control module (EBCM) • The front passenger door module (FPDM) • The HVAC control module • The inflatable restraint sensing and diagnostic module (SDM) • The instrument panel cluster (IPC) • The memory seat module (MSM) • The powertrain control module (PCM) • The radio • The radio amplifier • The rear seat audio (RSA) controller • The rear seat entertainment (RSE) assembly w/U42 • The rear wheel steering control module • The remote playback device-CD player w/U1S • The transfer case shift control module • The transmission control module (TCM) w/Allison transmission • The theft deterrent control module • The vehicle communication interface module (VCIM) w/UE1

best bet is to stop in at a Pep Boys, Autozone, or similar big autoparts seller, and ask for free trouble code scan, which should pinpoint area causing problem. If not obvious by codes, what is necessary to repair the problem code, get back to us with those codes and we will be glad to assist you further. Better this way, takes away the guess work, and saves you money, as well as getting it right the first time.

Check you leads on your throttle body plug. This is a GM problem but they have not had enough complaints to recall any vehicles. Some other GM vehicles have the same issue and the dealer can't seem to solve it or acknowledge the problem.

2004 chevy express van codes p0894


P0894 Transmission Slipping
P1258 Engine got Hot
P1516 Throttle Actuator Control (TAC)

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. over-hood-250x300.gifThe codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.

The reduce engine light comes on at 50 mph what could the problem be


DTC P0120 P0220 P1516 P2135 these should be the problem codes.
2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer. for reduced engine power. p0120 is throttle position sensor, ( tps ). p0220 is relates to tps, p1516 tps is out of range. p2135 is a throttle body code, the throttle body needs replaced. but before you do it replace tps first to see if it takes care of the other codes. have a good day !!
