p0351 code loss of power 2.3L08ford ranger,it warms slow and really need to eliminate1~voltage regulator is where?) & 2~ ground through PCM) 3~knowing limits&threashholds{sensorsIGNcircuit}?Ty 0$


P0351 loss of power ? That's not what this code is about . P0351 - Ignition Coil A Primary/Secondary Circuit ,you have a bad coil and possibly a bad coil driver inside the PCM . Do yourself a favor an take your vehicle to a qualified repair shop !
P0351 - Ignition Coil A Primary/Secondary Circuit Description: See the description for DTC P0350. Possible Causes: See the possible causes for DTC P0350. Diagnostic Aids: See the diagnostic aids for DTC P0350. Application Key On Engine Off Key On Engine Running Continuous Memory Coil-on-plug (COP) ignition testing - GO to Pinpoint Test JF . GO to Pinpoint Test JF . Coil pack ignition testing - GO to Pinpoint Test JE . GO to Pinpoint Test JE .
P0350 - Ignition Coil Primary/Secondary Circuit Description: Each ignition primary circuit is continuously monitored. The test fails when the powertrain control module (PCM) does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module (integrated in the PCM). Possible Causes:
  • Open or short in the ignition START/RUN circuit
  • Open coil driver circuit
  • Coil driver circuit short to ground
  • Damaged coil
  • Coil driver circuit short to VPWR
Diagnostic Aids: Use the 12-volt non-powered test lamp to verify START/RUN voltage at the ignition coil harness connector.
Check the coil driver circuit for open, short to VPWR, or short to ground. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test JE .

loaction 2004 Dodge Durango code P0058


following answer courtesy of OBD-CODES,com P0058 HO2S Heater Control Circuit High (Bank 2 Sensor 2) OBD-II Trouble Code Technical Description Article by Dale Dale Toalston ASE Certified Technician Generic: HO2S Heater Control Circuit High (Bank 2 Sensor 2) Nissan: Heated oxygen sensor (HO2S) 2 Bank 2 - heater voltage high What does that mean? This code is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model. Oxygen sensors with a heating element are common on today's engines. Heated Oxygen sensors (HO2S) are inputs used by the PCM (Powertrain Control Module) to determine oxygen content in the exhaust system. The PCM uses the information gained from the Bank 2,2 HO2S mainly to monitor the efficiency of the catalytic converter. Integral to this sensor is a heater element. While in pre-OBD II vehicles an Oxygen sensor was a one wire sensor, now they are more commonly 4 wire sensors: Two dedicated to the oxygen sensor and two dedicated to the heater element. The oxygen sensor heater basically decreases the time needed to achieve closed loop. The PCM controls the heater on-time. The PCM also continuously monitors the heater circuits for abnormal voltages or in some cases, even abnormal amperages. Depending on the make of vehicle, the Oxygen sensor heater is controlled one of two ways. (1) The PCM directly controls the voltage feed to the heater either directly or via a HO2S relay and a ground is supplied from the vehicle's common ground. (2) There is a fused 12 volt Battery feed (B+) that feeds 12 volts to the heater element anytime the ignition is on and the control of the heater is done by a driver in the PCM which controls the ground side of the heater circuit. Finding out which one you have is important because the PCM activates the heater under various circumstances. If the PCM detects an abnormally high voltage condition on the heater circuit, P0058 may set. This code is only referring to the heating circuitry half of the Oxygen sensor. Bank 2 is the side of the engine that does not contain cylinder #1. Symptoms Symptoms of a P0058 DTC may include: MIL (Malfunction indicator lamp) illumination There would likely be no other symptoms. Causes Potential causes of a P0058 code include: Faulty Bank 2,2 HO2S (Heated Oxygen sensor) Open in the heater control circuit (12 volt PCM controlled systems) Short to B+ (battery voltage) in the heater control circuit (12 volt PCM controlled systems) Open ground circuit (12 volt PCM controlled systems) Short to ground on heater control circuit (On PCM ground controlled systems) Possible Solutions First, do a visual inspection of the Bank 2, 2 HO2S (heated oxygen sensor) and it's wiring harness. If there is any damage to the sensor or any damage to the wiring, fix it as needed. Check for bare wires where wiring enters sensor. This often can fatigue and cause shorts. Make sure wiring is routed away from exhaust. Repair wiring or replace sensor as necessary If all appears okay, unplug the Bank 2,2 HO2S and verify that there is 12 volts B+ present with the key on engine off, (or ground is present, depending on the system). Verify the heater control (ground) circuit is intact. If so, remove the o2 sensor and inspect for damage. If you have access to resistance specifications you can use a Ohmmeter to perform a resistance test of the heater element. In

code p0443


Fault Code:- P0443 Indicates a Power-train fault


The fault is generally due to a problem in the Emission Control area


Fault Description: EVAP canister purge valve circuit malfunction

Action of ECM:- ECM Default: - Canister purge inhibited - Adaptive fuel metering inhibited


After clearing the DTC, complete the Purge system monitor drivecycle
Check for a reoccurrence of fault DTC.


Possible Fault:- EVAP Canister purge valve to ECM drive circuit: open circuit, short circuit, high resistance EVAP Canister purge valve power supply circuit: open circuit, short circuit EVAP Canister purge valve operating vacuum hose leak / restriction EVAP Canister purge valve failure

What does the diagnostic code P0446 for a 2001 isuzu rodeo mean?


Hi, your vent valve has malfuntioned. The vent valve is near the tank, and has a hose to the tank and a solenoid to close it. Check the wiring/connector. If OK, try applying 12 volts directly to the solenoid. If it does not click when voltage is applied, replace the solenoid/valve.

P0446 Evaporative Emmission Control System Vent Control Circuit OBD-II Trouble Code Technical Description

Evaporative Emission Control System Vent Control Circuit Malfunction
What does that mean? Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.
Symptoms There will be no obvious symptoms to driver, other than MIL illumination.
Causes A code P0446 could mean one or more of the following has happened:

  • Faulty vent valve
  • Open, short or excessive resistance on Vent valve control circuit
  • Blockage of vent valve
  • Bad PCM
Possible Solutions With a P0446 OBD-II trouble code, here are some things to try:
  • Replace Vent valve
  • Repair open, short, or resistance problem in control circuit
  • Repair open, or short, or resistance problem in power circuit
  • Replace PCM
