No start replaced timing belt and resealed cam carrier now wont start and po342 cam sensor signal high in ecm?

if spark and fuel possible belt improperly replaced - timing maybe off--ecm not flashed correctly for vehicle

Inspect the reluctor wheel for signs of damage or looseness. Refer to Diagnostic Aids. If you find damage or looseness to the reluctor wheel, refer to Camshaft Replacement - Left Side in Engine Mechanical.
Did you find and correct the condition?

Diagnostic Aids
• The following conditions may cause this DTC to set:
- Camshaft reluctor wheel damage
- Incorrect sensor installation
- The sensor coming in contact with the reluctor wheel
- Excessive air gap between the reluctor wheel and the sensor magnet
- A cracked or damaged sensor
- Foreign material passing between the sensor and the reluctor wheel
• This DTC will set with an intermittent failure on the ignition 1 voltage circuit, the CMP sensor signal circuit, or the low reference circuit. A hard failure of any one of these circuits should set DTC P0342 or P0343.
• The CMP sensor low reference circuit is shared with the mass air flow (MAF) sensor, and the engine coolant temperature (ECT) sensor.

The camshaft position (CMP) sensor is a hall effect switching device that works in conjunction with a single tooth reluctor wheel used to determine the position of the bank 2 exhaust camshaft. The engine control module (ECM) expects the CMP sensor signal to be low, 0 volts, as the single tooth in the reluctor wheel passes the sensor, and high, 12 volts, during the remainder of the reluctor wheel rotation. The ECM supplies a 12-volt pull up voltage on the CMP sensor signal circuit. The ECM expects to see one transition from high to low every two crankshaft revolutions. This signal, when combined with the crankshaft position (CKP) sensor signal, enables the ECM to properly synchronize ignition timing, fuel delivery and knock control. As long as the CKP signal is available, the engine can start and run. The ECM will default to a non-sequential fuel injector operation even if there is no CMP sensor signal. If the ECM detects extra or missing CMP sensor signal transitions within a certain number of crankshaft revolutions, DTC P0341 sets.
The CMP sensor has the following circuits:
• Ignition 1 voltage circuit
• Low Reference circuit
• CMP sensor signal circuit

DTC P2089 A - Camshaft Pos Actuator Ctrl Circ Hi Bank1
On this code the cam or crank sensor is normally the culprit. I would replace the crankshaft position sensor. There is anothe possible sensor that can cause this to happen vehicle speed sensor and engine coolant temp sensor. The way it works is The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range. But the most common problem is the cam or crank sensor Start with the crankshaft sensor and then camshaft sensor.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

If you disconnect the Cam sensor with key on or engine running then you will get a Cam sensor code,If you disconnect and the vehicle runs yes you will get a Cam code (because its disconnected it will state Cam sensor high),If your vehicle has jump timing belt you will also get a MAF code. You may want to get the MAF check out,For now review your timing marks

Honda P0370 - Timing Reference High Resolution Signal A Malfunction.

The optical sensor provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse.

Possible Causes:
- Open or short in the optical sensor circuit
- Optical sensor connector
- Damaged optical sensor
- Damaged PCM
- Damaged ECM

Possible Solutions:
- If damaged repair the optical sensor circuit
- Replace optical sensor
- Replace PCM
- Replace ECM

Not sure where you got incorrect gear ratio. This P0370 DTC is for what I have listed above.

HI, ok lets address each issue as your asked 1. Timing belt: since this engine uses a timing chain and it runs fine for the most part its unlikely to be the cause. 2. Ignition module: well the module not only sends the signal for spark timing but it also uses another signal for the fuel injectors. Since these ignition modules are very sensitive to heat the module may fail only when it is hot. So yes it could be the ignition module. 3. A fuel problem: Because you have fuel that sprays a foot high does not mean it has proper pressure. think of it as a garden hose the water flows out the end of the hose normally but when you place your thumb over the hose it squirts harder. You are trying to release the fuel from a much larger fuel rail threw a small shrader valve. Electric fuel pumps are little motors turning at very high rpms. when they get hot after use they draw more amperage and produce less volume and pressure. So yes fuel could be the issue. 3. Injectors clogged: Your right unlikely but you may want to do a resistance check of the injectors while cold then one while hot. You may find even one shorting out after it gets hot and this will shut down the whole bank of them. 4. Crank sensor: the crank sensor sends a pulse to the DIS module the ECM then controls the demand for fuel and timing. These crank sensors are prone to cracking and letting oil wick into the sensor apply heat and it can raise the resistance and make the sensor fail till it cools. So yes the crank sensor can cause this type of no start. 5. Cam sensor: no this model 3.1 did not use a cam sensor. 6. Intake gaskets: this would have to be one very large leak when hot. you could try pouring oil over the intake gasket area while cranking and see if it fires over. The oil is should be heavy and thick enough to seal it for a short time or show where it sucks it in. a few things you over looked are the importance that the temp sensor and TPS sensor play during a hot start. If the ECM thinks that the engine is cold it uses injector pulse like a choke on a carburetor. Good luck on your adventure I hope this has helped.

It soundslike your timing belt may have a problem. It may have failed prematurely, thetensioner may have failed, the tensioner pulley or idler pulley may have wornout, or the timing may be incorrectly set. No spark can usually be guaranteed acrank sensor fault, cam sensor fault, or timing fault. If the timing checksout, maybe you got a bad crank sensor or cam sensor, but I am 98% sure it'srelated to timing.

hi either you got a wire shorted out or the ecm failed on ya.
another thing to check is timing belt or chain you couldve popped the belt or jumped timing and the syncroing is off or got a bad ground.to check the timing belt loosen a few of the top screw on the timing cover and shine a light down there to see if the cams are turning if they are so far so good.then get a scanner on the car and see if the crank and/or cam signal is there and go from there.

it could be the cam sensor try that first before spending money on that in a shop

Check the ECM if it has the number 1228253 on it, this is what is wrong with it. Gm trashed all of these bad ecms. Get a 16198264 as they do not cause a cutting off problem . Get a delco ecm , aftermarket units will give trouble and may be a rebuilt 1228253 which is junk.
