P0340

Some of the common causes of Diagnostic Trouble Code P0340 (https://www.yourmechanic.com/article/p0340-obd-ii-trouble-code-camshaft-position-sensor-circuit-malfunction-by-jamahl-walker) include camshaft position sensor circuit wiring that is broken, shorted, or corroded; a camshaft position sensor circuit connector that is broken, shorted, or corroded; a faulty camshaft position sensor;...

The P0340 problem code references a camshaft position sensor (https://www.yourmechanic.com/services/camshaft-position-sensor-replacement) malfunction. The ability to restart the engine suggests it is failing versus has failed. There was an issue with this engine with the cam chain tensioner - which also affects...

Hi there. Typically, when a vehicle is hard to ignite, it's related to ignition timing. However, there is no need to spend $2,500 from the dealership on that type of repair. The best thing you can do is contact one...

Hey there. As you know, this P0340 code (https://www.yourmechanic.com/article/p0340-obd-ii-trouble-code-camshaft-position-sensor-circuit-malfunction-by-jamahl-walker) indicates the camshaft position sensor (https://www.yourmechanic.com/services/camshaft-position-sensor-replacement) is either faulty or not connected properly. The camshaft position sensor monitors the speed of the camshaft providing the ECU with this information. The ECU...

Hi there, thanks for writing in. This engine does not have a camshaft sensor, but uses the ignition module to detect when cylinder number 1 and 3 are at top dead center using the coils internal circuits. You may need...

Hi there. These codes (https://www.yourmechanic.com/article/how-to-read-and-understand-check-engine-light-codes-by-jason-unrau) may or may not be related to one another. I would be most concerned with the high idle first. Most of the time, on this engine it is due to a bad vacuum line. It...

These codes both indicate a problem with the cam sensor for bank 1, or A, on the passenger's side of the engine. Whether the sensor has failed and no other problems exist would need to be verified. I would recommend...

Hello. Code P0340 (https://www.yourmechanic.com/article/p0340-obd-ii-trouble-code-camshaft-position-sensor-circuit-malfunction-by-jamahl-walker) sets due to many possible faults. The sensors themselves have to be tested using an oscilloscope to see if the output waveform meets spec. If the sensors were not tested, there may have been nothing wrong...

Hi there. The codes are coming up for the camshaft position sensor (https://www.yourmechanic.com/services/camshaft-position-sensor-replacement), Oxygen sensor (https://www.yourmechanic.com/services/oxygen-sensor-replacement), EGR valve (https://www.yourmechanic.com/services/exhaust-gas-recirculation-egr-valve-replacement), and evaporative (https://www.yourmechanic.com/services/canister-purge-solenoid-replacement) system not working. The fuses for EMS1 and EMS2 and the main relay vary depending on what Aveo...

Since the crank position sensor gets its timing signal off the damper, I would first replace the damper to be sure timing was correct. The fact that this failure occurs after a "heat soak" cycle, and the P0340 code is...

Hello. P0340 is the trouble code for an issue with the vehicle's camshaft position circuit. The circuit includes the sensor built into the distributor, as well as the wiring that carries the signal to the computer. If the distributor is...

Hi, thanks for your question about the P0340 trouble code (https://www.yourmechanic.com/article/p0340-obd-ii-trouble-code-camshaft-position-sensor-circuit-malfunction-by-jamahl-walker). The camshaft sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-camshaft-position-sensor) on the Lexus ES300 should be located toward the back of the motor on the right side (assuming you are facing the motor) near the...

Hello. Cleaning the throttle body and idle valve may have been needed, but the intermittent starting and dying symptom can be the camshaft (https://www.yourmechanic.com/services/camshaft-position-sensor-replacement) and crankshaft sensors (https://www.yourmechanic.com/services/crankshaft-position-sensor-replacement). These are the codes P0335 (https://www.yourmechanic.com/article/p0335-obd-ii-trouble-code-crankshaft-position-sensor-a-circuit-malfunction-by-spencer-clayton) and P0340 (https://www.yourmechanic.com/article/p0340-obd-ii-trouble-code-camshaft-position-sensor-circuit-malfunction-by-jamahl-walker). The code P0446...
